graphviz.dart #

A Dart package and Emscripten module for Graphviz.

Usage #

To render as SVG (produces an XML string):

var svg = graphviz("digraph { a -> b; }", render: Render.SVG);

To prevent UI freeze graph layout may be computed in a separate thread using Web Workers:

var gv = new Graphviz();
gv.layout("digraph { a -> b; }").then((String result) {
  print(result);
});

Try comparing page load and refresh times between Firefox and other browsers.

Set the current Emscripten path:

cd /path/to/emsdk_portable/
source ./emsdk_env.sh

Build the Graphviz Emscripten module:

emmake make clean all

This project is based on work by Mike Daines, Satoshi Ueyama and Brenton Partridge:
