Visualize Sorting Algorithm Online
Watch bubble, selection, insertion, merge, quick, and heap sort run step by step — animated bars, comparison and write counters, plain-English narration, and complexity cards. Use Sorting Algorithm Visualizer in your browser with no signup, no daily limit, and no backend processing for tool input.
Problem
You need a quick visual read on structured data before building a dashboard, report, or notebook.
What to do
A quick chart can reveal patterns, outliers, and missing values faster than scanning rows by hand.
- 1Load the data into Sorting Algorithm Visualizer.
- 2Choose columns, grouping, and chart options.
- 3Export the chart or continue refining the dataset.

Sorting Algorithm Visualizer animates bubble, selection, insertion, merge, quick, and heap sort on bars that physically slide past each other when they swap. Every comparison shows a colored TRUE/FALSE verdict, the pseudocode highlights the running line, and live counters track comparisons and writes — so the O(n²) vs O(n log n) difference stops being abstract.
People also ask
- Why do the bars slide instead of jumping?
- Each bar keeps a stable identity, and its position animates when a swap moves it — the slide IS the swap, which makes the algorithm's data movement visible.
- What do the colors mean?
- Amber bars are being compared, red bars are being moved or written, violet marks the pivot or key, and green bars are locked in their final sorted position.
- Can I sort my own numbers?
- Yes — open "Use my own numbers" and paste up to 120 values separated by commas or spaces.
