Here’s a sample of a poorly done chart. Stephen rightly points out two major issues that make this misleading: a non-zero baseline, and discontinuous time frame on the X axis. I would probably add that the side-by-side column format makes aggregate comparisons of the two data series hard to digest.

Now here is Steve’s redesign of the chart. The problems identified have all been fixed in an elegant and highly functional chart. My only *small* nit with the reworked version is that the years only show up on the bottom-most chart of the three, forcing the viewer to scan down to the bottom of a long graphic in order to understand the time scale of data points at the top.

Here’s a wonderful resource: Places and Spaces: Mapping Science, a 10-year effort to build a collection of maps to encourage a “cross-disciplinary discussion on how to best track and communicate human activity and scientific progress on a global scale.”  The maps are physical artifacts but the online gallery is deep and very well done.

The variety of representation modes in the collection is very broad, ranging from things we would recognize as maps, to Mignard’s “Napoleon’s March to Moscow” chart made famous by Tufte, to some visualizations whose beauty may outstrip their explanatory power such as this one by Ingo Günther.

For a good book on the subject of maps and science, check out Atlas of Science: Visualizing What We Know by Katy Borner (link goes to Amazon).

If you’re looking build a data-access capability, these folks can probably help.

Among other things, Nathan has built a list of Data and Visualization Blogs Worth Following, which is a great resource in its own right.

While Nathan shares a wide variety of serious tools, there’s humor in there too. Check out this one reblogged from Doghouse Diaries:

In his written summary, Stewart Brand introduces Rumsey’s talk as follows:

“Once an artist, long a real estate success, now one of the world’s leading historic map collectors and THE leading online map innovator, David Rumsey gives an exceptionally deft graphic talk. Complex and elegant things kept happening with his images, always on cue with never a hesitation or false move. I’ve never seen a tighter weaving of ideas, words, and persuasive images.”

It’s a great lecture, and offers just a taste of the incredibly powerful resource Rumsey has built through years of passionate collecting, visionary sharing, and financial support. Check out Rumsey’s webste: http://www.davidrumsey.com/
