The duo leading the design firm onformative, talk on Skype. A lot. This infographic summarizes their interaction between 2008 and 2010: messages sent, characters typed, and files sent.
The large bubbles represent the number of files sent. Red indicating files sent from Julia to Cedric, black are files sent from Cedric to Julia. As your eye vertically falls down the poster progresses from 2008 to 2011. The vertical axis shows the number of characters typed.
The radar plots show the messages sent by type. The circle essentially representing a 24-hour clock. On the right is a standard, but pleasing, area plot showing number of characters typed. To the left are bubble plots showing the share of characters typed.
I enjoy the neutral colors with subtle patterns to separate areas of the chart. Although one can point to a few shortcomings—such as the use of bubble plots in the lower-left corner—it is an excellent source for inspiration for an upcoming project.
