QGeoJson Document wrong

QGeoJson class document has a json like below

{ "type" : "Point","data" : [60.0, 11.0] }

but this is not a valid Geojson. When we use QGeoJson::importGeoJson to get a QVariantList, we will get a QGeoCircle with a nan center, which will confuse beginner.

maybe we can change it to

{ "type" : "Point","coordinates" : [60.0, 11.0] }
