About

An interesting blog post from David Robinson (a data scientist at Stack Overflow) inspired me to revisit an old experiment I made called Flight Stream. I wanted to make it more generally useful for illustrating flow between sets of points on the earth and also make it support lots more points. David was kind enough to share the source data from his post with me and I used it to make the changes. As per the blog post, this visualization represents a days worth of global information exchange on Stack Overflow (data is anonymized). The flow direction is from the person who answered to the person who asked.

Use the mouse plus left-button to spin or mouse wheel to zoom. The Controls panel lets you experiment with the visuals.
