@aru_sas I think variable mapping is still one of the very human elements of data. In general, I think more is better in the data collection and structuring phase; any trait that is directly related to your primary key should potentially be included. You can always leave out data in a visualization.

Blogger

@Houngbo - For very large datasets, I would recommend animation if there is a time series component or a word cloud if it is language based. It is very hard to use a static visualization for large datasets without getting overwhelmed and drill down often can get very granular and leave you 6 levels down trying to look for something,

Blogger

@dslakeland With Stephen Few, I tend to think of this work as focusing on simplicity. I'm a big fan of simple and practical visualization in general. But it's important not to confuse simple with sophisticated and cutting edge. One can still use animation, 3-D, mapping, or anything else and still have a conceptually simple visualization.

Blogger

@dslakeland Wayne at least used to have this view of data analysis vs data reporting: analysis is for discovery while reporting is more static. I think the two worlds are coming together and that reporting should have an analysis or interactivity aspect to it. I'll be honest; I haven't spoken with Wayne recently about visualization, specifically.

Blogger

Well you caught my attention with the super-sized headline!

Blogger

Here is an interesting data visualization resource: Dynamic Data Visualizations in the Browser Using Shiny and R language

Dynamic Data Visualizations in the Browser Using Shiny

Prospector

Thank you Hyoun. Great presentation, with lots of great tips. 

Blogger

Second, remember that visualization is a first step we're taking into data interaction. We are just starting to learn how to really use data, so keep your eyes open on how you can take the next steps into data immersion.

Blogger

First, I will get to everybody else's questions later today. Thank you so much for being here!

Blogger

Thanks for a great session

Blogger

@TheRizza - Ask your end users what they would want next or how they would want to dig into existing visualizations.

Blogger

I do like that Rule of 7! (and the Hero's Story, as well). Those are great to keep in mind.

Blogger

Great session today, Hyoun, thank you!!!!

Data Doctor

Hyoun, any last thoughts you'd like to leave our attendees with?

Blogger

@BethSchultz - For keeping a visualization simple, the key is in keeping the view simple and relevant: Rule of 7 and using the appropriate visualization type.  Let the end user dig in as much as they want, but don't make their view so cluttered that they can't understand what they see.

Blogger

Attendees, we're heading into the top of our hour. If you have any questions for Hyoun, please be sure to get them posted!

Blogger

@RenatoCL - Free tools really depend on what you're looking for. Javascript libraries are free. Visual.ly and Wolfram Alpha are free. R and OpenLayers are free. But each of those is different.

Blogger

Hyoun, I create visualizations, but rarely get feedback on what I create. I get better suggestions from my wife than my customers! Any suggestions on how to force feedback as part of the process? In the corporate world, they are usually just happy to have data to look at and rarely refine the first draft.

Prospector

Thank you Hyoun for the presentation. Most of the analysis I do can be shown in a bar on line chart. It can be tempting to "jazz up" the charts by using 3d. I will not do even think about doing that again :-)

Prospector

I concur Mr. Park.

Prospector

The interactivity levels must be tied to each end user's needs

Prospector

@Hyoun: How do you evaluate a visualization? 

 

Prospector

@pkilaruoud The GIS tools are great for demographic work and as a starting point for coordinate-based visualization. Because they have to render information at such a granular level, they can often also be a good starting point for visual drill downs of information

Blogger

Its an excellent point templates can also help with story telling

Blogger

Hyoun, during the lecture you talked about the importance of keeping the interactivity built into a visualizaiton simple enough. Are there any rules of thumb for knowing when enough is enough and the interactivity is getting too complicated?

Blogger

Is there any free software you recomend for data visualization?

Prospector

I would presume different users would require different analysis and hence visualizations.

Prospector

@Houngbo - Visualization as a scalable capability requires developing a process to consistently translate data into visualization and it has to take into account: data management, BI, and front-end development. Ideally, you would develop front-end templates for your major use cases rather than simply reinvent the wheel for each visualization

Blogger

@BethSchultz - different types of visualization should only occur if different types of analysis are taking place. If all analysis is categorical, sticking to a bar-based or word-based visualization is probably OK.

Blogger

@pkilaruoad -- so same visualization, different levels of interactivity based on role-based access -- similar to what you'd find with a management or other dashboard?

Blogger

@Hyoun, in your comment to @sungkim you suggest figuring out end user requests for interactivity. That's an interesting point, I think. I would imagine this is less asking them how interactive they want the visualization to be and more about asking the views of the data they'd like -- and then figuring out the level of interactivity from there. Is that about right?

Blogger

@Hyoun "Develop visualization as a scalable capability rather than a consistent one-­-off challenge." Can you elaborate?

Prospector

dslakeland - I think the future of visualization is about greater immersion. This is pie in the sky, but consider that we can smell certain scents at a part per billion.  Why not use that as part of our understanding of data?

Blogger

Ideally one should create visualizations with different levels of complexity and give acces to users based on thoer needs.

 

Prospector

Must go. Great takeaways, Brain heavier than what I started with. Much thanks!

Blogger

@Sungkim - For time vs perfection, the real keys are to to start with figuring out scope, end user requests for interactivity, and a basic viz structure. I've always worked in enterprise environments where time is of the essence. Also, don't be afraid to hand off a data-ready framework to a front-end developer who can jazz up your work.

Blogger

Hyoun, have you joined us?

Blogger

Hyoun, one of the questions I have deals with the level of interactivity to build into a visualization. I would think this would sometimes vary by the intended user -- which could get problematic if more than one user type (executive board vs. business managers, for example) are viewing the same visualization. Do we sometimes need to create more than one version of a visualization to provide different levels of interactivity?

Blogger

Hyoun, great presentation. Clear, concise, informative, good visuals!

Blogger

For demographics you may want to try GIS systems...there are some tools avilable.

Prospector

@Hyoun: Good visualization might require front-end programming skills - I agree! 

Prospector

I'd be interested in Mr Park's view on the Visualization theories of under-opinionated Wayne Eckerson and over-opinionated Stephen Few?

Yes, indeed it was a nice presentaition !!

Prospector

bulk I agree if the visualization muddys the waters then its not useful

Blogger

Nice presentation Hyoun!

Data Doctor

What is the future of Visualization?

 

Question: what are some suggestions for dealing with time vs perfection challenge?

 

Prospector

Thank you so much for showing up here! I'll start at the top, but feel free to repost any questions from the bottom if I'm not getting to them

Blogger

Great presentation Hyoun, really enjoyed this! 

Data Doctor

Great presentation - Thank you

 

Any tips fo data viz displaying demographic info etc. on maps?

Blogger

@lyndon : That is a nice way to win over an argument !!

Prospector

What tools, payed and free, do you recomend to create good data visualization?

Prospector

easy to read and simple to use, pretty much the best advice for visulization IMO

Data Doctor

I often use data viz to win an argument

Blogger

A successful visualization should highlight important information about the data

Prospector

A successful visualization should be able to reveal trends, patterns, gaps, and/or outliers.

Prospector

Getting to the point of vizualization "scalable capability" is a real challenge that's for sure, at least trying to do it inexpensively and quickly

Data Doctor

Yeah letting the end user dig into the data seems to open up a lot of productivity from the end users

Data Doctor

Here's a data viz tool that probably took years

http://www.allanalytics.com/author.asp?section_id=2310&doc_id=268018&

Blogger

damn, 6-8 weeks!!!!! man! 

Data Doctor

The end user like our organizaton still have a way to go to develop great interactive visualization on our own. The "7" idea is a good reminder to keep the category numbers down for viewers to understand better what we're telling in the charts

Data Doctor

@Hyoun: You are right, understanding human visual perception can help us develop more effective visualizations. 

Prospector

slide 19 makes you think the analysis was very difficult and advanced. Unfortunately, when you make things easy to understand some people think it was easy to obtain.

Prospector

I remember this from a phyc class I took as an undergrad. 

Data Doctor

Maybe we're used to remembering phone numbers? (7 digits)

Blogger

bulk do you thing most people understand how to read work clouds

Blogger

My word cloud looked nothing like this :-( just a handful of words. LOL

Data Doctor

Yeah, slide 19 looked like some kind of molecular-atomic structure

Blogger

The lack of stardarization of data visualization tools has been a challenge in how and what to choose to simplify our data charting so we don't end up with those complex but "beautiful" charts

Data Doctor

@Lyndon -- maybe the live infog is interactive?

Blogger

I have to say that does look amazing. 

Data Doctor

It really is pretty but I agree most people dont have that talent or time

Blogger

Missing how this is interactive ... I think of interactive as cliciking on points or other graphics and getting data displayed

Blogger

I remember reading about use of analytics of hardcore baskeball fans a few years ago durring the whole Linsanity thing

Data Doctor

I have heard about visual analytics being used in base ball and now it is in basket ball too..nice to know !!

Prospector

In Semiology of Graphics (83) Bertin defined a set of visual attributes such as: Position, size, value, texture, color, orientation and shape

Prospector

It does a trend summary might also be useful

Blogger

THose charts came from MSN..i think.

 

Prospector

Those lat/long numbers are a good example of how the detail gets lost in the reality of what it really represents

Data Doctor

The two chart example in slides 14 and 15 really does make a big difference. 

Data Doctor

The time-based mapped Google data chart example certainly illustrates well how the simple time chart can be easier to understand with just a few changes in the display. Are you listening, Google?

Data Doctor

@Beth, I was thinking the same thing, but I think there has to be a lot of control with the experience there to make sure its used to bring across the message you want. 

Data Doctor

summary text is useful for visualization it helps users draw the appropriate conclusions

Blogger

Visualizations express some facts in the set of data, not necessary all the facts. 

Prospector

I really like the idea of letting the end user take over the story. That's a good way to think about interactive visualizations

Blogger

Normal world and clients can be so borrrring

Blogger

I always hate to leave the Reward

Blogger

@Maryam: That makes sense!

Prospector

That is true, @Lyndon!

Blogger

The special world can be a lot more fun, especially for those nerdally inclined

Blogger

Hospice sometimes is better to tell the story in segments to achieve the best understanding especially with visualizations

Blogger

@beth I did not know Joseph Campbell either; glas I'm not the only one

Prospector

Joseph Campbell related anthropology with religion, myth, etc. sorta like Jung

Blogger

Aha! I see where he's going with this. Interesting!

Blogger

I like the visulization that tell a story, it really makes the data stick to me. 

Data Doctor

I use tableau and sas visual analytics for visualizing large datasets, but again not every company can afford the cost associated with these costly softwares !!

Prospector

Who knows Joseph Campbell? I must confess to not!

Blogger

The Joseph Campbell hero's journey is an interesting take on using data and story telling narratives to help make the data clearer with vizualization

Data Doctor

@Maryam: OK! Is it possible to know the whole story about your dataset or you try to represent part of the story? 

Prospector

Data doctor it is true sometimes simplicity is much more powerful than complexity. Visualization should help the story easier for lay people to undersand.

Blogger

on the lines of Hospice - is there a good way to present variables during model selection

Prospector

Hospice I think its possible when you know what your story is...

Blogger

Even simple Google data maps are becoming increasing complex not to mention users' ability to customize maps with more data making them even more difficult to see the real picture from the data.

Data Doctor

What is the efficient way to visualize large datasets? Is that even possible?

Prospector

What do we think of the infographic boom its the everyday visualization we see.

Blogger

I think in some cases 3D viz can look classy

http://austinrailnow.files.wordpress.com/2014/04/1_arn_barchart_rail-revote-delay.jpg

 

Blogger

How to get interactive visualization without a lot of added complexity is a real challenge for us.

Data Doctor

@Beth, I do, all the time when I present my research data. And the group I present to always give me feed back that they think it is a good chart for my data set. 

Data Doctor

I tend to think of the word cloud as kind of passe, vs of real analytic value

Blogger

Beth I confess we still use them for market share data!

Blogger

@Beth, great point, that is probably the only thing it showed me. I think they are a great tool for sites with larger range or content, just not so much when there is a narow focus. 

Data Doctor

'Fess up -- who uses pie charts regularly?

Blogger

Pie charts are even worse when you can not print in color

Prospector

@bulk -- at least, maybe, it showed you were consistent in content!

Blogger

@Beth: Not that I am doubtful, but not that convinced 

Prospector

Is anyone using new tools or software for visualizations? Do you like these new tools?

Blogger

@Beth, when I added it I was excited because I thought it would be a good feature but after a year in it just highlighted 4 or 5 words that were the main focus of my blog. 

Data Doctor

What is the future of Visualization?

 

Clusters, word clouds and maps are taking over everywhere and more familiar now to most users, bye bye our old 3D pie charts which we though were so cool!

Data Doctor

@ke, it's on the left of the player above

Blogger

good point, @bulk, about word clouds. sometimes they really don't serve much purpose!

Blogger

@hospice -- you sound doubtful (or am I reading your comment incorrectly?)

Blogger

do not see start button

Prospector

I used to have a word cloud on my blog, to highlight all my tags, but I pretty much blog about the same few topics so it wasnt too exciting. 

Data Doctor

There is a historical paradygm in place about visualization. Right!

Prospector

@ke -- click the start button on the player above, and follow along with the slide deck provided at the link above.

Blogger

@dave.terlaje -- try clicking on the left-hand arrow on the player in the window above. The audio is streamed, and some browsers have trouble with it.

Blogger

i do not hear anything

Prospector

I have played around with some of the tools, but still struggle with brining across the data the way I want it to. 

 

Data Doctor

I certainly grew up with the line and bar charts and tables back in the early days of the Apple computer which at the time we thought was truly amazing as data could so easily be manipulated by novices and viewed via very simple chart designs.

Data Doctor

@Sungkim: Did you download the slide show?

Prospector

how to join the web serminar

Prospector

has the broadcast started?  I hear nothing.

Prospector

@sungkim - yes, this is audio only. You'll need to download the slide deck from the link above, and follow along with Hyoun.

Blogger

Hello everybody. While Hyoun takes us into the program, anybody willing to share their experience with data visualization so far? How interactive are yours?

Blogger

is this just audio conference?

 

Prospector

Hey Everyone, excited for today! 

Data Doctor

Interesting question, @dslakeland... We'll have to ask Hyoun when he joins us here for Q&A after the audio lecture concludes. Stay tuned...

Blogger

I'd be interested in Mr Park's view on the Visualization theories of under-opinionated Wayne Eckerson and over-opinionated Stephen Few?

 

Participants, please note that the audio player for today's lecture will appear in the window above at start time. If it doesn't start automatically, please click the left arrow. If you have troubled with the audio stream, you might try another browser.

Blogger

As folks join in, please remember to download the slide deck for today's lecture by clicking on the link above (next to Hyoun's headshot). Hyoun will be using the slide deck in his lecture.

Blogger

Today's All Analytics Academy class will be starting at the top of the hour, at 2 p.m. ET. Joining us will be Hyoun Park, who is a founder and principal consultant at DataHive Consulting. I'm looking forward to hearing what he has to say about creating interactive data visualizations, as I know visualization is a particular passion of his.

Blogger

So, this is actually a combination of several challenges. One is around the initial development of relevant data access through appropriate data structures. One is around coordinating both developers and analysts to have access. And one is around convincing other stakeholders regarding the value of data experimentation.

I'll talk about some of the pitfalls that prevent dynamic data visualizations from being adopted and how to get consensus towards becoming more data-oriented as an organization. The convincing process and politics can often be more challenging than the actual work!

Blogger
Full understanding of the capabilities requires full access to production data logs from different sources. This access remains a constraint to developers and analysts. Is there any good way to convince how experimenting with the data can be beneficial?
