Finally, I decide to implement one last Friday noon. After a few hours, I had a basic Treemap class in python. When I was testing the class, I found the algorithm can generate some interesting artistic painting effect.

The following is a composition using the Gene Ontology. I guess this is one of the many ways to visualize the so-called Systems Biology. You can also click on the image to see some other randomly generated compositions.

Inspired by Newsmap, I tried to see if I can use the python Treemap class and some javascript to map Diggs to a treemap. So, I spent a few hours in the last weekend making this little toy — Diggs in A Box.

It is rather primitive now and I can think a long TODO list to improve it. Hopefully, I will get some time to improve its functionality and appearance eventually. If you have any suggestions, please leave a message and I hope you find such presentation of data interesting and useful.
