This is Algovis, an algorithm visualization project, created by Isaiah Damron.
Algovis is still in initial development ("Alpha", if you will). Currently, it only supports sorting algorithms and only one type of visualization, but there are more to come. Also, there's no way to save the code you write, other than copy and paste of course!
Note that this has only been tested on Mozilla Firefox and Google Chrome. Also, the apparent speed of each algorithm can be deceiving, because of the hooks needed to support the visualization.
Any feedback or help would be appreciated at Github. Have fun!
