> why not from code?

We build networks of lots of different kinds against our own codebases and databases. And personally I've done a bunch of experiments around visualizing code in the past.

Unfortunately, I don't think I, or anyone else at the company, has convincingly cracked the problem yet. Generally, the visualizations look pretty, but they aren't "tactile" or practical enough to be useful.

But you've convinced me that it would be worth digging up some of my old experiments and writing a blog post around them, so that at least any progress I've made can be carried further by other people.
