## What it is
Algorithm Visualizer is an interactive online platform that visualizes algorithms from code, letting users watch algorithms execute step by step. It is a React web app backed by a server, algorithm visualization repositories, and tracer libraries in multiple programming languages.

## Use cases
- visualize sorting algorithms step by step
- learn how graph traversal algorithms work
- teach data structures and algorithms to students
- see how code maps to algorithm behavior
- explore algorithm tutorials with animations
- understand recursion and dynamic programming visually

## When to choose
- you want an interactive, visual way to learn or teach algorithms
- you need a free open-source tool for computer science education
- you want to see algorithms from code executed with animations in the browser

## When to avoid
- you need a production algorithm library to call from your own code
- you require offline desktop use without a browser
- you need exhaustive coverage of every algorithm or the latest research algorithms

## Facets
- artifact type: application
- maturity: stable
- function: data-visualization, animation
- domain: education, web-development, tutorials
- platform: cross-platform
- tags: algorithm-visualization, data-structures, interactive-learning, react, computer-science, education, algorithms, web-server, nodejs
