graph‑draw is a JavaScript library that takes an undirected planar graph (a list of vertex coordinates and edges) and fast‑generates a tessellation of the graph’s thickened strokes into convex polygons (3–8 sides), suitable for rendering with WebGL, Canvas or map overlays. It is aimed at developers who need high‑performance, low‑overdraw drawing of network‑like shapes—e.g., map boundaries, polylines, railways, or any planar graph visualisation—in both Node.js and browsers.
