This project is a Makefile for building Graphviz with Emscripten and a simple wrapper for using it in the browser.

Download the viz.js "binary" from the releases page.

There is one function, Viz.

Viz(src, options={ format="svg", engine="dot" })

Some examples:

Viz("digraph g { a -> b; }");
Viz("graph G { n0 -- n1 -- n2 -- n3 -- n0; }", { engine: "neato" });
Viz("digraph g { x -> y -> z; }", { format: "plain" });

These engines are supported:

• dot
• neato
• circo
• twopi
• fdp

These formats are supported:

• svg
• xdot
• plain
• ps

To build from source, you will need to install the Emscripten SDK: http://kripken.github.io/emscripten-site/docs/getting_started/index.html

To download the sources and build everything:

make
