Welcome to Chechu’s sorting visualiser! Here, you can see how different sorting algorithms work on a variety of customisable data sets, all in real-time. I’ve optimised my visualiser to run smoothly on all devices, and I’ve added a speed slider and an element selector to allow you to customise your experience. Plus, I’ve added a unique satisfying touch by incorporating sound, in the form of a frequency for each value.

Whether you’re just curious, a beginner looking to understand the basics of sorting, or a more advanced user looking to compare the performance of different algorithms, my visualiser has something to offer you.

My visualiser will be including a range of popular sorting algorithms soon in time, while for the moment there is only selection sort and insertion sort, there's no limit other than imagination to which algorithms to include: Bubble sort, merge sort, quick sort, radix sort… All of them and more are going to get into this website soon!

You can select the algorithm you want to see in action, choose how many elements you want to sort, shuffle it, and there you go! As the algorithm works, you’ll see the data being sorted in real time, making it easy to understand the steps involved.

You can also see the big O notation of each algorithm and compare it with an easy-to-understand table showing how many operations have been made in real time along with many other details.
