This is chord diagram showing the structure of the LSST Transients and Variable Stars Collaboration - TVS and the affiliation to LSST TVS subgroups. Each pair linked by a chord represents two subgroup affiliations that are shared by a number of members proportional to the width of the chord.

Roll over each wedge to see more information about each subgroup pair and on the arc to know more about the subgroup. The code is on github, text is parsed in gathered and python and the graphics is created in d3, leveraging heavilyb> off this demo blogpost by Steve Hall
