Tom Gonzalez has written an excellent post on how he’s come up with a new visualization method he’s calling Stacked Wedge Graph. The Stacked Wedge displays hierarchal data on a radial system. By splitting up the sectors of a simple Pie Chart and on different rings.
He argues that this approach was ignited by a client’s requirement he could not implement and still sustain the visual quality he stives for in his work. So the article is not just a great introduction in his thought on the Stacked Wedge but also on the collaboration with a client with already fixed ideas on the desired visualization method.
