Great presentation. Thank you for including all the examples and explaining the thought process behind choosing them.

would have been cool to mention some of the sources. Recognized some of work from Hans Rosling (Gapminder) and Ben Fry (Processing).

This is so cool.

Good examples used.

Great visualization of cluster analysis. What tools did you use for this analysis ?

Where to find the scatter analysis tool?
