## What it is
JointJS is an open-source JavaScript/TypeScript diagramming library for building interactive, production-scale diagram applications using SVG. It is framework-agnostic with first-class React support, and a commercial JointJS+ extension adds pre-built UI components, automatic layout, and BPMN shapes.

## Use cases
- build an interactive flowchart editor in the browser
- create a drag-and-drop AI workflow builder
- embed a BPMN process modeler in a web app
- build a node-based visual programming or low-code editor
- render SCADA/HMI monitoring dashboards with diagrams
- build an org chart or data modeling tool
- create an ER diagram or network topology editor

## When to choose
- you need fully interactive, customizable SVG diagrams in a web app
- you want a mature, proven library (since 2011) with TypeScript support
- you need framework-agnostic diagramming that works with React, Angular, Vue, or Svelte
- you are building complex node-and-edge editors like workflow or agent builders

## When to avoid
- you only need static charts or plots - a charting library like D3 or Chart.js is simpler
- you need built-in automatic layout, BPMN shapes, or export features without paying for the commercial JointJS+ tier
- you need canvas/WebGL rendering for tens of thousands of elements
- your project requires a permissive open-source license (JointJS is MPL-2.0, and key features are paid)
