I made a tool to visualize sorting algos https://xosh.org/VisualizingSorts/sorting.html where you can put your own algo too if you like.

I love the idea behind that sorting visualization, and found it extremely useful to validate the properties of my Quicksort implementation.

That's interesting. Alas, it only works for in-place sorting algorithms (and it's also an animation).
