Sika Graph is a TypeScript library that takes raw node, link and group definitions (optionally filtered) and runs a D3‑style force simulation to produce ready‑to‑plot graph data, including node positions, group hulls and simulation metadata. It’s aimed at front‑end developers building interactive, physics‑based network visualisations—especially within educational tools—who want a simple API to generate stable layouts without manual force‑engine handling.
