 | *map*.**csvDataSource**([*value*]) | Object | null | To load statistical data from a CSV file, set this parameter with an object *{ url: "", geoCol: "", valueCol: ""}* where *url* is the URL to get the file, *geoCol* is the column where the NUTS_ID is specified, and *valueCol* is the column containing the statistical values. |

 | *map*.**scale**([*value*]) | String | *"20M"* | The simplification level of the map, among *"10M"*, *"20M"*, *"60M"*. The most simplified version is *"60M"*. |
-| *map*.**scaleExtent**([*value*]) | Array | *[1,4]* | The zoom extent. The first value within [0,1] defines the maximum zoom out - the second value within [1,infinity] defines the maximum zoom in. Set to null or *[1,1]* to forbid zooming. |
