Algorithm Visualizer - Intuitive Sorting/Search/Pathfinding Animation
The Algorithm Visualizer is a free online educational tool that helps you intuitively understand classic algorithms through animated demonstrations. Supports 6 sorting algorithms with real-time comparison, swap, and sorting process visualization.
Supported Sorting Algorithms
- Bubble Sort: O(n²) - Simple but inefficient, repeatedly compares adjacent elements
- Selection Sort: O(n²) - Selects minimum element each iteration
- Insertion Sort: O(n²) - Efficient for nearly sorted data
- Quick Sort: O(n log n) avg - Divide and conquer with pivot partitioning
- Merge Sort: O(n log n) - Divide and conquer with recursive merging
- Heap Sort: O(n log n) - In-place sort using heap data structure
FAQ
What is algorithm visualization?▼
Algorithm visualization uses animation and graphics to show how algorithms execute, helping learners intuitively understand algorithm workings and compare efficiency differences.
Which sorting algorithms are supported?▼
Bubble Sort, Selection Sort, Insertion Sort, Quick Sort, Merge Sort, and Heap Sort. Compare execution speed and comparison counts.
Can I customize the data?▼
Yes. Random data generation, adjustable array size and value range, and animation speed control.
How does visualization help learning?▼
Makes abstract processes intuitive, helps understand each step, time complexity differences, and why certain algorithms are more efficient. Ideal for beginners and interview prep.
Is data uploaded?▼
No. All execution and rendering happens locally in the browser. No data is uploaded.
