TO DO NEXT: Try last effort(described below) at making quartile legend. If that fails put the ugly-code matplotlib legend solution back in (it's hiding in the "copy". To do: Map Tiles Scale ?side by side maps point people towards the folium examples on github Clean up code and what not Write an intro (that includes the fact i'm looking for a job outside of teaching ASAP (but in portland):p) Write prose to explain any complicated bit Write conclusion about limitations ?Figure out how to deal with massive file sizes Figure out how to get it to the web for sharing
