Graphviz compiled to WebAssembly (@hpcc-js/wasm-graphviz 1.30) runs inside a sandboxed Chrome renderer with network blocked, so a pathological graph cannot exhaust the API process. Syntax errors return the Graphviz message; file-reading attributes (image, shapefile, imagepath) and javascript: links are rejected. Node, edge and cluster counts come from the SVG; PNG is rasterised by Chrome.
