Happy new year…
I did to clear circles from display :
hast_source = GeoJSONDataSource(geojson=hast_geojson) # it works as circles
…
…
#Here I want to remove points from display by means of:
#assigning empty geojson to GeoJSONDataSource
empty_geojson=’{“type”: “FeatureCollection”, “features”: }’
hast_source.geojson=empty_geojson
But it failed in terms of cleaning the existing circles.
