dotgraph

javascript parser and library for the Graphviz dot/xdot format, implimented based on the grammar defined http://www.graphviz.org/doc/info/lang.html provides a parser based on PEG.js and some javascript objects for manipulating and querying graph properties.

Basic Usage

ast = DotParser.parse(str_source);
graph = new DotGraph(ast);
graph.walk();   // walks the ast and gathers all information about nodes, edges, and subgraphs

console.log(graph.nodes);   // object of all nodes and their attrs
console.log(graph.edges);   // object of all edges and their attrs
console.log(graph.graphs);  // object of all subgraphs and their attrs

XDotGraph is a subclass of DotGraph that parses all the recognized xdot attributes and turns them into javascript objects, automatically converting inches to pixels where applicable. Note: the list of recognized attributes is currently very short, consisting of pos (for nodes and edges), width, height, bb, lp
