Following on from the retro heat map, how about a standup heat map?

David Colls realised that his standup had become 2 separate conversations: the team’s shared conversation at standup had been lost.  So he made a map of who spoke to whom at standup to show what was really going on. With the team currently working on 2 pieces of work which were not directly related to each other the dialogue was fragmenting. A good topic for retro?
