   I'm able to get it working for point data (e.g. GeoJSON in EPSG 4326 CRS) 
but not for Polygon data:
   
   Here are some examples that should be fairly easy to reproduce. These make 
use of the SQL editor and I'm using the amancevice docker container (v0.37.2).
   
   Running a query to create a rectangular polygon (using PostGIS):
   `SELECT 1 as mock_data, ST_MakeEnvelope(-0.127677, 51.507515, -0.122161, 
51.510021, 4326) as geom;`
   
   Gives a jagged polygon (instead of rectangular):

   Similarly, when casting the geometry to Well Known Text format:
   `SELECT 1 as mock_data, ST_AsText(ST_MakeEnvelope(-0.127677, 51.507515, 
-0.122161, 51.510021, 4326)) as geom;`
   
   <img width="1589" alt="Screen Shot 2020-11-10 at 11 46 36" 
src="https://user-images.githubusercontent.com/4347878/98671479-3cd4d580-234c-11eb-82d8-21590a117656.png";>
   
   And with GeoJSON it displays nothing:
   `SELECT 1 as mock_data, ST_AsGeoJSON(ST_MakeEnvelope(-0.127677, 51.507515, 
-0.122161, 51.510021, 4326)) as geom;`
   <img width="1585" alt="Screen Shot 2020-11-10 at 11 49 50" 
src="https://user-images.githubusercontent.com/4347878/98671551-5aa23a80-234c-11eb-838c-41b7420c4c04.png";>
   
   Any information or advice on how to display a polygon would be much 
appreciated.
   
   Thanks.
