Very nice!

I would love to see something like this but for all supermarkets around the world with prices in local currencies adjusted.

i.e.

Where is the cheapest place in the world to buy a banana?

Where is the most expensive place in the world to buy a banana?

Now the 'banana' -- could be any food item, it doesn't matter.

A future tool like this could be able to help future societies predict which areas of the world are in economic ascent and which are in economic decline (cheaper prices = economic ascent, expensive prices = approaching potential future economic peak and/or approaching potential future economic decline, etc.)

Anyway, looks great!
