Old school D3 from simpler times
Polygons with multiple popups open Fav DC spots
Here's a little map of my favorite two tourist spots I hit up on my recent trip (April 2014) to Washington DC. The two places highlighted are the National Botanical Garden and the Thomas Jefferson Building Library of Congress.
I wanted to get multiple popups being open at the same time to work with the typical map loading method but failed. Maybe I have to use stuff like that as is if I do the L.mapbox.map thing???
Oh well if you have a day free in DC and haven't checked out these two free destinations I highly recommend them.
Plus if you know how to make the mapbox.js api to work with multiple popups as I confusedly described above let me know.
