Graphviz vs Sigma.js
Both stand on graph visualization tools software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APILinuxMac+2
Choose Graphviz if you want free, open-source graph visualization with configurable layouts and broad export options. Look elsewhere if you need a Visio replacement or prefer a workflow other than describing graphs in text.

Sigma.js offers a focused browser library for interactive Graphology visualizations, with WebGL performance, framework support, and extensibility packages. Developers should prepare graph data and choose npm when production bundle size makes tree-shaking important.

Graphviz: what it does well
- Free and open source under the Eclipse Public License.
- Exports to image, document, and graph-related formats.
- Offers multiple layout programs and algorithms.
- Customizes graph, node, edge, and cluster attributes.
- Documentation covers library use; external resources list language bindings.
What to know first
- Graph descriptions use a simple text language.
- The project says it is not a Visio replacement.
- DOT is the only listed import format.
Sigma.js: what it does well
- Free MIT-licensed library
- WebGL rendering for large graph displays
- Built-in pan, zoom, hover, and touch interactions
- Works with React, Angular, Vue, or vanilla JavaScript
- Companion packages add maps and image export
What to know first
- Requires Graphology graph data
- A sized container DOM element is required
- Browser bundle includes the whole library
- TypeScript-only exports are unavailable at runtime
