The Visual Art Behind Data Science


All Analytics readers like data visualizations -- even though slightly more than 50 percent of the participants in our recent quick poll conceded "the quality is inconsistent."

While none of the 65 respondents explained exactly what they meant by that inconsistency, it's easy to surmise.

And I don't think I can state it any better than Ryan Bell, a user interface developer for EffectiveUI, a digital user experience agency:
As available data becomes more complex and extensive, weaving it into a visualization that invites engagement, understanding, and decision-making is a bigger challenge, with a bigger opportunity for payoff.
Bigger opportunities for payoff -- but, in the wrong hands, those turn into greater opportunities for misinterpretation, especially when we expand the term "data visualizations" to include infographics.

There are so many infographics these days, and so many of them are cluttered, confusing, and, unfortunately, wrong.

Remember that infographic Dylan Matthews at The Washington Post published last month under the headline, "The saddest graph you'll see today"?

The infographic was created by the Enliven Project to put the legal issues around rape, its prosecutions, and concerns about false accusations into perspective. The idea was to visualize the fact that false rape accusations are rare. But critics claim the infographic was misleading in several ways because it assumed one-rape-per-rapist, overestimated the number of unreported rapes, and overestimated the number of false accusations.

Good intentions can get lost pretty easily in a bad data visualization.

Effective data visualizations marry art and science. They transform complete and accurate data with sound visual design elements, like line, form, shape, value, and color. But to do that, and create a visualization that keeps the data in the right context, the graphic artist has to understand the information being visualized.

It's all about the data. As David McCandless, a London-based independent data journalist and information designer, explains, the key to a great data visualization is "good, tight, and comprehensive" data. "The technical term for that is 'juicy.' Juicy data. In fact, 80 percent of the work involved in creating an infographic is data-gathering, shaping, and checking. Making the data juicy," he states.

So, here is the question: How can data professionals and graphic artists work better together to bring data to life -- beautifully, effectively, and without distortion?

Hi Noreen, I don't really think the Enliven Project data visualization was so horrible myself. It certainly met its mission of raising awareness, even more so because of the brouhaha that followed from it! The lesson I take from it is that at times data visualizations are meant to be taken more conceptually than in hard numbers -- but the designers and editors must make that distinction clear in their presentation.

Wow. The rape one is very powerful.

One of the most helpful data representations I receive comes in the form of our electricity and water bill. At the back of the bill you get two graphs showing the national average for water and electricity consumption for my house type along with my monthly consumption. This generates awareness. Inevitably if I have consumed more than the national average I would become more conscious about that fact. The next month I would most likely try to conserve more.

SAS has a nice blog post on Make better business decisions with Visual Analytics

Take a look.

Nice is a 4-letter word for "We're screwed."

Noreen - Whoa boy. I guess this falls into the "good" data visualization but showing a bad result. About the only improvement that would help the visualization is to put a piece of toast on the Really Scary Things row next to the "Ocean floor methane released causing runaway climate change. Possiblity of mass extinction."

At least it will only take up to 300,000 years to re-absorb the atmosphere's CO2 and we can start over again.

I'm not sure about that. My household consumption is so out of whack in the energy report comparison my electric utility sends me that I find it really hard to believe its using good comparables. I don't think, for example, that it's enough to show comparisons between houses on the same block. My house is virtually the same as the one two doors down -- except there only two people are in residence and here five (and six when my daughter is home from college). That's generally three times the amount of laundry being done, and dishes, and cooking, etc. Plus there's the fact that I work in a home office, and so on.

I like to compare my own usage year-over-year and my electric bill lets me do that with a simple bar graph
