About sorting visualiser
I've been writing sorting algorithm articles since Merge Sort back in 2012. I try to focus my articles on quality and ease of understanding, using images where relevant to help with that. Sorting visualiser was built to complement the articles by animating each comparison and element move to help get a better understanding of the algorithms.
Check out the code for the sorting visualiser on GitHub.
