A very simple "choropleth" style map with tooltips with D3. All you need is a GeoJSON of polygons.

See code.minnpost.com/simple-map-d3 for instructions, configuration, and examples.

1. Install NodeJS.
2. Install Grunt: npm install -g grunt-cli
3. Install Bower: npm install -g bower
4. Install packages: npm install && bower install

1. Run: grunt

There are some very basic tests in the tests/ folder. Run them like so: node tests/core.js

As this library depends heavily on D3 and SVG, Simple Map will only work in "modern" browsers. The following is some basic tests run on Tesling.
