In late November, Chris Ingraham posted his interactive remake of a radial network diagram of state-level U.S. migration data. He’s asking the community for alternative approaches. Below is a sample of the text from the alternative on his bl.ocks page, but check out the full post for all the details. The data come from existing tabulations from the 2012 American Community Survey. (Please note that this is a request for help with an interactive visualization.)

“I thought there might be a better way to display these data, but I wasn’t right. I stuck with a map, drawing circles for each state sized by net migration (comings minus goings) and colored according to whether the state gained or lost residents overall. To get at individual state flows, click a state – paths radiate inwards and outwards from state to state, depending on the net migration flow between the two.”
