Viz.js is a WebAssembly build of Graphviz with a JavaScript wrapper, allowing DOT graph descriptions to be rendered as SVG in the browser or Node.js. It also includes CodeMirror language support for the DOT language.
Use cases
- render graphviz dot diagrams in the browser
- convert dot notation to svg
- display dependency graphs on a webpage
- render flowcharts from dot source in javascript
- visualize network graphs client-side without a server
- syntax highlighting for graphviz dot in code editor
When to choose
- you need to render Graphviz graphs entirely client-side in a web app
- you want to avoid server-side Graphviz installation
- you need SVG output from DOT source in JavaScript
When to avoid
- you need extremely large or performance-critical graph rendering
- you need interactive graph editing rather than static rendering
- you are not working in a JavaScript/WASM-capable environment
