Have a look at the site here.

This repository (and the site above) contains visualizations for various sorting algorithms.
It can be used as a teaching resource as it provides quite a lot of information along with visual insights on the algorithms.

The source code for the processing sketches are stored in the processing_source_code directory.
It can be run using the Processing 3 IDE or using Eclipse IDE with some minor changes.

Comparison sorts

• insertion sort
• bubble sort
• selection sort
• quick sort
• merge sort
• heap sort
• gnome sort
• cocktail shaker sort
• cycle sort
• shell sort

Non-comparison sorts

• radix sort
• counting sort
• bucket sort

The visualizations exist for the checked ones, for the others I'm still either understanding/implementing/writing visualization code.
