Sorting Algorithm Visualizer
Watch and learn how popular sorting algorithms work behind the scenes. This interactive tool visualizes algorithms like Bubble Sort, Selection Sort, and Insertion Sort in real-time. Adjust the animation speed and generate new random arrays to see how the algorithms behave under different conditions.
How to Use It
Select an algorithm and animation speed, generate a new random array, then press play to watch it sort step by step.
Example
Watching Bubble Sort on a 20-element array visually shows adjacent elements repeatedly swapping until the whole array is in order.
Common Use Cases
- Studying data structures and algorithms coursework visually.
- Comparing the relative speed and behavior of different sorting algorithms.
FAQs
Which sorting algorithm is fastest?
It depends on the input size and data — for large datasets, algorithms like Merge Sort or Quick Sort generally outperform simpler ones like Bubble Sort, which this visualizer helps make visible.
Is this an online sort algorithm tool, or do I need to install anything?
It's fully online — this algorithm visualizer runs entirely in your browser, with nothing to download or install. Just pick an algorithm and press play.
Is there a sorting algorithm visualiser with adjustable speed?
Yes — use the Animation Speed slider to slow the visualiser down and study each comparison and swap step by step, or speed it up to see the full sort complete in a couple of seconds.
Is this algorithm visualizer online free to use?
Yes, it's completely free with no sign-up — generate a new random array and run Bubble Sort, Selection Sort, or Insertion Sort as many times as you like.
