In short, I agree with most of the arguments put forward, but I disagree with the conclusions:
- I agree that my 3-D graduated symbol maps are "pure chart junk", but there are some good examples of 3-D symbol maps. (See previous blog post)
- I disagree that 3-D prism maps are chart junk - but thematic world maps on a 3-D globe are problematic. (See previous blog posts: , , ).
- I very much disagree that Virtual Globes are a bad idea for thematic mapping, but it's certainly not the only or the ultimate way of showing thematic maps.
