Łukasz Kostka designed this linking visual to show the connections between the board members in the WSE WIG20.

A map of connections between board of directors and supervisory board members in companies forming WSE WIG20 index. Connection is assumed if two people are members of the same board. Dot size reflects a number of boards. Link color reflects a number of connections.

I had to lookup what the WSE WIG20 was, and according to Bloomberg “The WIG20 index is a modified capitalization-weighted index of 20 Polish stocks which are listed on the main market. The index is the underlying instrument for futures transactions listed on the Warsaw Stock Exchange.”

I wish there was a good way to also see which companies are represented along with their board members.

Thanks to Łukasz for sending in the link!
