The map allows you to compare the prices charged by MacDonald's, Chick-Fil-A, Taco Bell and Chipotle across the whole of the US.

Select one of these four fast food chains and you can view a choropleth map comparing the price of the chain's signature dish at all its outlets across the country. On the map the United States is divided using a voronoi layer based on the nearest fast food outlet. This means that if you zoom in on your home on the map the choropleth layer shows the price at your nearest outlet. If you zoom-in on a fast food outlet you can view the actual price of its signature dish as a label on the map.
