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?

Hi, I use the Chord Diagram to visualize my own data, but I find a bug. This is the description figure:
https://lh3.googleusercontent.com/tn2BlSPfXgKgZ8FpswcwSeM7oTzwUGUpcjacVU_W70Y=w536-h873-no
From this figure, we see that the display has errors. I just copy the original code and replace the matrix array. Could someone help me solve this issue? Thank you so much!
