what I want to get from software visualization is being able to understand the code base better. But so far I haven't seen any visualization tool can do it.

The most famous code visualization tool is perhaps https://gource.io/

the only information I can get from looking at its results is "projects grow", which is something I can conclude without the visualization.

why is 3d treemap better than looking at folders (2d treemap)?

It's the aerial view vs the address book difference. The intent is to draw dependencies as underground pipes: you select a building and see what it's connected to.

This isn't a startup: it's just a side project that I've spent maybe 12 hours on.
