Love the detail and thought that has been put into this post, along with the other blog posts as well. Visualizations and animations go along way. A very ascetically pleasing site that is informative as well.
I agree on the aesthetic quality of the entire site.
Given the amount of detail included in the post, I was surprised that the author didn't mention that the primitives used in the d attribute for the <path> element allow one to synthesise most of the other SVG elements ... or did I just miss that somewhere?
