An attempt at data visualization

Good afternoon:

I'm in the process of learning how to work with D3 and had started working
on CSS data visualizations. Currently I have 2:

Was this like what you had in mind in this morning's call?

As part of the visualizations I've started building a JSON object with CSS
properties that you can use for your projects.

Please let me know if there's anything else you'd like to add. Currently
I'm working on adding hyperlinks from the leafs (the object farthest to the
right) of the visualization to the corresponding pages in the webplatform
website. If you want to tweak the code or the JSON object, I set it up on
github: https://github.com/caraya/data-vis

Let me know what you think
