@Brian27, you're taking us way back here! I've not heard of cardiac before this mention -- pretty cool, really. I bet you could never have envisioned where we are today with computing even in your wildest of imaginations!

In my senior year high school, physics class, each student received a computer - a paper one, from Bell Laboratories, called cardiac "A cardboard illustrative aid to computation". http://www.beatriceco.com/bti/porticus/bell/belllabs_kits_cardiac.html Until that point, the only computers I had seen were in books or on TV; it was fascinating to get my hands on my own.
In the same class, we did some lab work with analog computers (think we had about 8 of them), each the size of a suitcase. The circuitry was very basic: plug-board connections, mechanical relays, switches, resistors, diodes, etc.... The "display" was in the form of a volt-meter. I thought these were cool too. The teacher let me play around with them after class; and I linked them together (basically working off the cardiac pattern), to make a digital computer - probably the world's least powerful.
A few years later, I was in a programmer/analyst curriculum. After being shown the computer room with it's IBM 360/370 (they had also gotten a mini-computer, with CRT terminals; and we played a bit with that after class), we almost never went near the computer again; we did all our coding on preprinted programming language specific, coding forms. We'd hand off the correlated sheets to data entry students, who entered our code and data onto punch-cards. These stacks of cards were sent to the computer operators for over-night batch processing; and we'd get the results the next morning, in the form of wide carriage dot-matrix printouts - so really, it was back to paper and pencil.
I did get to see some data visualization: as a student rep, I got the chance to attend a "World Computer Conference" in NYC. What I really remember from that trip was the impression that no one person could possibly know all there was to know about computers and information systems - and that was in the 1970s.

We've got artiness, computer graphics, machine learning, databases, psychology, "computer vision" -- not to mention stats and other math. That's quite a list of requisite skills for somebody who wants to hone their visual analytics talent!
