 # Processing in QGIS
 To create a political/religious/provinces/culture/etc. map use _Vector_ -> _Geoprocessing Tools_ -> _Dissolve..._ and select the .geojson file as input and the attribute you want to merge by (e.g. "state"). QGIS will merge all the polygons that share the same attribute so that you end up with one multipolygon per state/culture/religion/etc.
