+ * ArrayData is useful when a numercal value is to be translated to
+ * something thats cannot directly be calculated from this value, this could for
+ * example be a dataset meant to plot population of various countries. Since x-
+ * values are numerical and they should really be country names, but there is no
+ * linear correlation between the number and the name, we use an array to 'map'
+ * the numbers to the name, i.e. $array[0] = 'Denmark'; $array[1] = 'Sweden';
+ * ..., where the indexes are the numerical values from the dataset. This is NOT
+ * 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.

+The [map name].png (fx. europe.png) is the actual image presenting the map. The

+named locations is written on every line with the x and y coordinates after the
