Visualize Binary Search Tree Online
Insert, delete, search, and traverse a BST, AVL tree (animated rotations with balance factors), or min-heap — every comparison narrated, every pointer move animated. Use Binary Search Tree 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 Binary Search Tree Visualizer.
- 2Choose columns, grouping, and chart options.
- 3Export the chart or continue refining the dataset.

Binary Search Tree Visualizer animates insertions, deletions, searches, and all four traversals on a BST — plus AVL trees with named, animated rotations and balance factors, and a min-heap shown as array and tree simultaneously. Every comparison is narrated as the walk happens, so you see exactly why each node lands where it does.
People also ask
- What's the difference between the BST and AVL tabs?
- Both are binary search trees, but AVL checks balance factors after every insertion and rotates to stay balanced — guaranteeing O(log n) height where a plain BST can degrade to O(n).
- How does deletion pick a replacement?
- A node with two children is replaced by its in-order successor — the smallest value in its right subtree. The animation walks to it so you see why it's the right choice.
- Why show the heap as an array AND a tree?
- Heaps are stored as arrays in practice (parent i, children 2i+1 and 2i+2). Watching both views swap in sync connects the theory to the implementation.
