Do you filter out data points within a given city? It seems like most couples would live in the same city...

Those data points appear as circular flashes without a line, there are quite a few of them there. The app appeals to a lot of long distance Couples so the map is somewhat biased towards long distance communication.

Also if you look at big cities (LA, NYC, SF) you'll see a continuous stream of circles flashing without lines. So the data just overlaps a lot.

Ah. I thought that was just artsy.

Very handsome visualization. I'm looking forward to the follow-up on how this was put together, especially the front-end.

This is a fantastic visualization. Would love to see as much as you're comfortable sharing with us!
