Free plan Web
NVD3 provides a free, reusable chart layer for D3.js web projects. Its broad examples and permissive license are balanced by an older D3 compatibility requirement and possible Windows workflow issues.

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.
