In the world of hockey statistics, context is everything. Player Usage Charts show how often a player starts in the offensive zone (horizontal axis), against how high a level of competition (vertical axis) and even how well the team does with him playing in those situations (the bubbles). These charts, the originals of which were explained in more detail by their lead innovator Rob Vollman in 2011-12's Player Usage Charts, have been brought to life and automated by visualization expert Robb Tufts, who can be reached through gmail (robbtufts.dataviz). Check out Robb's instructional video for an overview of some of the truly amazing things you can do with these automated Player Usage Charts. For any other questions, comments and suggestions contact Rob Vollman.
