I wrote some similar code in python recently -- I think color visualizations like this are both fun and potentially useful for certain image manipulations.

This includes a readable 36-line implementation of k-means clustering that could be shorter if one wanted to play some code golf :) I used a pie chart layout, with pie slices proportional to their corresponding cluster sizes.

If anyone else is interested in this stuff, Austin A made a great suggestion on the original post to use the Lab colorspace.
