Then I cleaned up the data by taking only the columns for state, county and total wheat production. This dataset includes a county 888 and 999 but that seems to be a combination of all the states counties so I stripped those out. Also there are more than 50 states in these county datasets which seems to be standard. There is always messing with numbers being seen as strings with these sorts of manipulations so some casting is needed.
The svg is 1.9 mbs and google drive does not want to store or convert it at the moment but if anyone wants it I can send it to them. This quality of file means zooming in on an individual state, like Kansas, is fine.
The code to create this picture is here.
I think I want Country_code and value for the commodity wheat in every country in the most recent year value. The country code is 2 characters (iso 3166-1 alpha 2) and the map I have from wikipedia is that format you can get it here
The code to produce colors for each country based on this data is here. Again this is based on the "Visualize This" book from Yau. This css code to set the color of each country gets pasted into the style section of the BlankMap-World6.svg file. I should read all the documentation describing the values before doing any analysis like this. But I am only doing this to make pretty pictures in Python so I am making assumptions to work quickly.
