Interactive Choropleth of the Number of States That Border Each State

This is a fun little map that shows the number of states that border each state. I’m working on improving the interactivity of maps and this was a good project to try this with. The base map is a choropleth map which color codes each state by the number of states it shares a border with. If you hover over (or touch on mobile) a state, it will highlight the state and show you (and list) the bordering states.

It’s important to note that officially New York and Rhode Island share a water border (between Rhode Island and Long Island, NY) and that Michigan and Minnesota also share a border (in Lake Superior).

Sources and Tools:

Data on state borders was downloaded from state.1keydata.com. And the visualization was created using javascript and the open source leaflet javascript mapping library.
