#Code Changes Tree Map
Run count_files.sh, passing a directory and a commit range you want to analyse. For example:
$ ./count_files.sh projects/neo4j HEAD~10..HEAD >data.tsv
Then start a web server and open index.html in your browser. Something like this:
$ python -m SimpleHTTPServer 8888 &
$ open http://localhost:8888/
A treemap recursively subdivides area into rectangles; the area of any node in the tree corresponds to its value. Treemap design invented by Ben Shneiderman. Squarified algorithm by Bruls, Huizing and van Wijk.
