Show HN: GitHub Treemaps

I really wish there was a good javascript implementation of cushioned treemaps (www.win.tue.nl/~vanwijk/ctm.pdf). The only implementation I've found so far is buried in a firefox plugin that gives a cushioned treemap of reddit comments(https://github.com/titusjan/plottit/blob/master/src%2Fchrome...), but I'd love to have one thats in a general purpose charting library.

There is a 'cargo cult' implementation in jit (https://github.com/philogb/jit/blob/master/Source%2FVisualiz...) - where they just fake some gradients to make pretend cusions, but its definitely not a true cushioned treemap, and adds nothing to the visual interpretation of the hierarchical structure of the data.

I guess I'll probably have to brush up on my JS skills and start blending things together.

Looking at this reminds me how small some projects are when you put things in perspective.

For example, most of the node.js project actually consists of less than ten developers. (http://tomiaijo.github.io/github-treemaps/#/repository/21166...).

Very Nice! Did you enter this into the data challenge?

Yep, let's see how it does :).

I'm not sure I understand anything new by looking at this. Cool graphics, but is there some key point i'm missing?

Personally I was interested in seeing how much different committers have contributed to projects. For example, Linus Torvalds and Git: http://tomiaijo.github.io/github-treemaps/#/repository/36502... .

Also it is quite interesting to see the different programming languages used in projects. For example, Git has almost as much Bash scripts as C code: http://tomiaijo.github.io/github-treemaps/#/repository/36502... .

Sort of. All of the test scripts are written in bourne shell. There are ~10K lines of bourne shell in git itself, and ~136K lines of test scripts.

That may be nitpicking, but I think it also goes to show that sometimes seemingly simple numbers or visualizations can miss subtle but important points.

Warning: can probably freeze you browser if you look at the most forked projects.

Most watched repos could be interesting too.

Unfortunately Github API does not provide means to search for most watched repositories. That being said, the front page listings are a small fraction of all repositories that I have treemapped so far (around 4000 at the moment). You can search all Github repositories from the search input, and queue them for treemapping if not explored already.
