Yes, the Recline viewer that CKAN uses supports all GeoJSON geometries.
The problem is that your polygons are not correct, you need:
- An extra set of
[]
around your coordinates (See the spec) - Close your polygons by repeating the first coordinate pair
So this file will work (you probably want 5 coordinate pairs to draw a square polygon):
