Flowing Data presents an interesting set of categories of people who are interested in data visualization. The list includes these five types:

• The Technician, focused on implementation (how the hardware/software support the visualization);
• The Analyzer, focused on the data (what are the numbers and what do they say?);
• The Artist, focused on the visuals (is it pretty?);
• The Outsider, focused on context (what's the other information we need to understand the data?); and
• The Light Bulb, focused on the picture -- the one with the Big Idea that everyone else has to sweat to implement.

Tasty Data Goodies, the blog from Swivel, talks about the five categories, and includes a graph purporting to show the relative size of the five types. Except the graph is based on a sample size of 10. And people could choose more than one category. I'm not reproducing the graph (you can see it here if you really want to), but why did they? I thought they knew data better than that. Just because you have some numbers doesn't mean you have information.

Back to the five categories. Do you see yourself in them? Your project partners (staff or volunteers)? Are these categorizations complete? Are they useful?

(As a side note, the Flowing Data blog is pretty neat -- I'm adding it to the blogroll on this page. If you have other suggestions for blogs that we should be linking to, please drop me a line.)
