This is fantastic visualization!
I couldn't figure out from the UI but is there a way to filter the map? Say, I only want to see things going out of Cusco or I only want to see where things end up in Berlin?
It would also be nice to have some directionality to the lines to indicate source and destination, perhaps a colour or lightness gradient or something.
Thanks! You actually can filter by source already, search lets you filter arcs by place/site. Destination filtering technically works too, via Collections, but that only makes sense while there are a handful, once it’s hundreds it’ll need its own proper destination filter. Good call on the color/gradient distinction for source vs. destination on the arcs too, that’s worth trying.
