An interesting site dedicated to Sankey Diagrams posted a nice article on our History of Political Parties and our civil war graphics. I highly recommend visiting this site to learn more about sankey diagrams.

From wikipedia …“Sankey diagrams are a specific type of flow diagram, in which the width of the arrows is shown proportionally to the flow quantity. They are typically used to visualize energy or material transfers between processes.”
