I love maps like these, the McDonald's (1) or Taco Bell one (2).

That said, these don't seem to cover things most people really buy - meat particularly, and fresh veggies. Or paper products. Have you considered adding more items?

It is not easy to get this kind of data as most of these companies do not provide any public APIs. I will continue exploring adding more products.
