I used the code that produced the video as a foundation to build interactivity into the map. The most significant visual change was the move to a dark background with bright data points. While I’m not entirely happy with the “civilization illuminating a dark continent” effect that might be communicated by this choice, I wanted to provide some variation in how opening dates were represented, and on monitors I’ve always found bright colors easier to distinguish from one another than dark.
