Visualizing Sorting Algorithms in Real Time

Sorting algorithms are one of the fundamental building blocks of computer science. While their source code is often only a few lines long, understanding how elements move through a collection can be much easier when the process is visualized.

This interactive demonstration allows you to watch several classic sorting algorithms operate on a randomized dataset in real time. Use the controls to choose an algorithm, adjust the animation speed, generate a new random sequence, and observe how the algorithm transforms an unsorted array into an ordered one.

During execution, the visualization highlights active comparisons and tracks the number of comparisons and swaps performed. These metrics help illustrate why different algorithms exhibit different performance characteristics and computational complexity.

Available algorithms:

• Bubble Sort — repeatedly compares adjacent elements and swaps them when they are out of order.
• Selection Sort — repeatedly finds the smallest remaining element and places it in its final position.
• Insertion Sort — incrementally builds a sorted section by inserting each new element into the correct location.

Try different speeds, randomize the dataset, and compare how each algorithm behaves as it processes the same input.
