Visualgo: Visualising data structures and algorithms through animation (visualgo.net)

Great website ! It's nice to see the different instructions while the animation is running.

I also use http://www.cs.usfca.edu/~galles/visualization/Algorithms.htm... when I want to visualize algorithms.

Few other helpful resources in the same vein -

This came up on HN a couple of months back - http://www.algomation.com/

A few sorting algorithms - http://corte.si/posts/code/visualisingsorting/index.html

Visualization of Path-Finding Algorithms - http://qiao.github.io/PathFinding.js/visual/

Lastly, Mike Bostock (creator of D3) has a really cool bunch of algorithms over at his blog - http://bost.ocks.org/mike/

Nice idea.

The interface feels a bit too busy and it is not clear on what to click on the details screen. Buttons at the bottom? Arrows on the right? Menu on the left? I was confused there for a while.

Oh, this is phenomenal. Not the visualizations alone, that's been done by others. But this site also has a "training" feature (top right button).

Try it out, it's great for learning/reviewing algorithms!
