[[Note: Please edit the title above and provide a description of the grid here.
Also check the ISO_3166-2 (https://en.wikipedia.org/wiki/ISO_3166-2)
codes if your grid uses countries or states/provinces. Finally, if you can
provide an example of your grid in action with a data set and sample code,
that would be great but is not required. Remove this text before submitting.]]
