I'm wondering what's the benefit of using d3 here compared to Leaflet's build-in geoJson() function: http://leafletjs.com/examples/choropleth.html#basic-states-m...

I used leaflet.js and d3 to highlight police zones in Atlanta for a friend: http://bl.ocks.org/elsherbini/82a63315d0d7c0cca2cd

TBT: d3/leaflet combination that renders geoJSON tiles http://bl.ocks.org/ZJONSSON/5529395 (still operational)

Cool! Needs 2012 tag though :)

Yeah was wondering what it was doing on HN, used this as a tute 2 years ago! :)

Doh, missed another one. Added!

I've got a few d3 + maps tutorial videos: https://www.youtube.com/playlist?list=PLI_sHchSmdCDH0ooOKSWS... Starting at #4 in the series I show how to use d3 + mapbox (basically Leaflet) and then d3 + mapbox-gl. Each video has associated blocks

This would be great to see school zone boundary demarcations, which can sometimes be quite important/contentious when looking for a new home.
