NUTS2 regions of Greece as coded by the Hellenic Statistical Authority, names in Greek

[[Note: To help streamline the process of adding this grid, please replace this text with an image of a map for the region for reference. Also, please 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.]]
