How to do algorithm visualization?

Question

I am looking for an algorithm visualization library/tool that is well documented and you can call from your source code.
I took a look at jhave - example of usage. And I liked it, it seems it has some documentation but I do not trust its future.
I found this article about Algorithm explorer it has a nice idea. It is implemented as a c++ api but I cannot find it anywere.

My main idea is that I want to do some unit tests for the brain.
So I construct various exercises and in future when I want to test my knowledge I redo them.
I found that images stick longer with me, so that is why I want to visualize algorithms in certain states. ( I might remember better a tricky case like what happens when data is sorted in reverse and I use quick sort if I view it.)

An ideal tool:
1. Has to integrate with any language.
2. Has to be well documented with a growing comunity and examples.
3. Be implemented on top of a capable rendering engine(ogre, xna).
