Map Layers, map players!
WSJ cartographer Renee Rigdon and I were feeling that AI2HTML wasn’t conducive for scrolly-telling, so I built a pared-down version that uses SVGs instead. Now we have a little utility that lets us use SVGs without having the text scale with the rest of the composition. With SVGs, it’s dead simple to turn on/off layers based on scroll events.
One successful usecase of th technogloy has been showing geo-political changes over time in a fixed area. You can see some demonstrations of this setup in a couple of projects:
Hopefully open sourcing this solution soon!
