summary

Shows server-side Canvas rendering using node-canvas and a fake DOM via jsdom, running a minimally patched flot to emit PNG streams and data URIs. Reuses client-side plotting code, accepts JSON via query string, preloads a shared document to avoid per-request DOM creation, and returns cacheable, opaque images suitable for wikis or embedded IMG tags. Tradeoffs are added server CPU and no client interactivity, but it works and preserves visual styling.
