.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Graph::D3 is a moudle to covert Graph object to the format which is used in d3.js(http://d3js.org/).
This module simply supports node-edge graph in the example.

.SS "force_directed_graph"
.IX Subsection "force_directed_graph"
This outputs the format which is used for Force Directed Graph described below.
.PP
https://gist.github.com/mbostock/4062045,http://bl.ocks.org/mbostock/4062045
.PP
The input graph should be directed grpah.
Node in Graph can have 'group' attribute (Default is all 1) to have different node color.
Also Edge in Graph can have 'value' attribe(defalut is all 1).
.SS "hierarchical_edge_bundling"
.IX Subsection "hierarchical_edge_bundling"
http://mbostock.github.io/d3/talk/20111116/bundle.html
.PP
The input graph shoudl be directed graph.
Node in Graph can have 'size' attribute (Default is all 1).
