Naomi's Graph Makeover Contest

Naomi Robbins has posted a contest, part 1 of which is to submit alternative representations for the following graph: Clearly, usage of two pie charts to represent the share of the B2B and B2C referrals will invite many responses. To create the graph, I took the data shown in the Pie Charts themselves, so we are using percent
