Chord Diagram

View README.md

Chord diagrams show directed relationships among a group of entities. This example also demonstrates simple interactivity by using mouseover filtering. Layout inspired by Martin Krzywinski's beautiful work on Circos.

Hi, I'm trying to play with this (http://mbostock.github.io/d3/talk/20111116/bundle.html) example with my own data. which has csv file contents as below:
source_proj ,issue_link, destination_proj ,dest_issuetype
[Inactive] Eikon Collab MM - Insider iPhone,Bug to Story,[Inactive] Eikon Collab MM - Insider iPhone,Story
[Inactive] Eikon Collab MM - Insider iPhone,jira_subtask_link,[Inactive] Eikon Collab MM - Insider iPhone,Acceptance Test
[Inactive] Eikon Collab MM - Insider iPhone,jira_subtask_link,[Inactive] Eikon Collab MM - Insider iPhone,Task

an so on.

can you guide me how to implement this graph with these four attribute. how to have relationship with them?

source_proj ,issue_link, destination_proj ,dest_issuetype

will this graph suit my requirement?
