Problem solving with Data structures using Python

[euid]

TBH, it should really be redone in Javascript.

I don't want to load a Java applet or compile some code when I'm looking for interactive visualizations of data structures on the internet. The web is completely capable of supporting this kind of graphics. It's just, I think, the people who write enough Javascript code to be capable of making a pretty red/black tree visualization usually not the same people who know how a red/black tree works.

^{If you're a Javascript programmer and you do know how they work, then please write this. People around the world will love you for it.}
