* values are numerical and they should really be country names, but there is no

* usefull when the x-values are a large domain, i.e. to map unix timestamps to
* date-strings for an x-axis. This is because the x-axis will selecte arbitrary
* values for labels, which would in principle require the ArrayData to hold
* values for every unix timestamp. However ArrayData can still be used to solve
* such a situation, since one can use another value for X-data in the dataset
* and then map this (smaller domain) value to a date. That is we for example
* instead of using the unix-timestamp we use value 0 to represent the 1st date,
* 1 to represent the next date, etc.

In this folder the files for the Image_Graph_Plot_Map are located. They should be the
following format:
[map name].png
[map name].txt
The [map name].png (fx. europe.png) is the actual image presenting the map. The
[map name].txt file is the location -> (x,y) conversion table. In this file the
named locations is written on every line with the x and y coordinates after the
name (with a TAB), i.e.:
Denmark 10 30
England 4 30
Where Denmark will be 'located' on (10, 30) on the map, and England at (4, 30).
No maps are released by default due to we want to avoid possible copyright issues.
