## What it is
Cytoscape.js is a fully featured graph theory (network) library written in pure JavaScript for modelling, analysing, and visualising relational data. It includes a graph model, many layout algorithms, and an optional interactive renderer that works in browsers and Node.js.

## Use cases
- visualise social networks in a web app
- render and analyse biological pathway graphs
- build an interactive network graph explorer with pan and zoom
- run graph theory algorithms like shortest path or centrality in Node.js
- display a dependency or knowledge graph in the browser
- apply automatic layouts like force-directed or hierarchical to node-link data

## When to choose
- you need both graph analysis and interactive visualisation in JavaScript
- you want a mature, MIT-licensed library with many layout algorithms and extensions
- you need browser and Node.js support for the same graph model

## When to avoid
- you only need simple static charts like bar or line charts
- you need large-scale server-side graph processing better suited to a graph database
- you need 3D graph rendering

## Facets
- artifact type: library
- maturity: stable
- function: data-visualization, charts
- domain: data-visualization, web-development, bioinformatics
- platform: browser, cross-platform
- tags: graph-theory, network-analysis, graph-visualization, interactive-graphs, javascript, algorithms, nodejs
