I'd like to point out that there has also been some research done in order to see how to exploit these sorts of "sketchy" visualizations for information visualization. This paper by Wood et al. contains some very nice example

I like "Computational topology" by Edelsbrunner and Harer. They start with some basic graph theory and build on that to give a solid overview of algebraic topology, persistent homology, and even some Morse theory.

Very good find, thanks for that. I recall that Peter Bubenik is working on a similar approach. His recent paper about "Persistence landscape" is also quite accessible, in my opinion: http://arxiv.org/abs/1207.6437

Certainly, I would be glad to discuss things as well. You can reach me as topolomancer (at) annwfn (dot) net.

Well, the thing about noise, from a topological point of view, is that persistent homology simply cannot decide whether something is noise or not --- at least not right away. To be more precise: A lot of what PH does is actually some sort
