I double DOG dare you to say it.

Actually, having some good datasets would be really helpful.  As pretty as bessel functions are, I'm rather tired of using them for all the basic chaco demos.

I vote for this as well.  The GIS data that is used for some of the older chaco examples is 2.6mb compressed, and I moved it out of the main enthought/src/lib/ directory structure for that reason.

The UN has a Statistics Division with tons of demographic data:

Now, granted, this is financial and demographic data instead of strictly scientific data, but perhaps the sheer volume and quality of the data outweighs the lack of direct scientific applicability.
