A hack to put Graphviz on the web. You should probably check out dagre, though:
https://github.com/cpettitt/dagre
https://github.com/cpettitt/dagre-d3
To render as SVG (produces an XML string):
svg = Viz("digraph { a -> b; }", "svg");
See examples here:

Compiled versions are available on the releases page:

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

Viz(src, format="svg", engine="dot", options=null)
- src is the string representation of the graph written in Dot language.
- format is the graph output format in terms of dot -T. Since the result of the function is returned as a string, the only sane formats are "dot" and "svg". Typically, one would use "svg" to display the rendered result.
- engine is the Graphviz layout engine to use. Can be any from "dot", "neato", "circo", "twopi" or others. Usually, one is satisfied with "dot" or "neato".
- options are the array of extra command line arguments which are virtually added to the corresponding engine invocation (thanks to GVC API's gvParseArgs()). To get an idea what such options can be, execute "dot --help" in your system's terminal. As an example, options=["-n"] makes neato enter "no layout" mode to render graphs already converted to "dot" output format as-is.
