Isochrone does not contain start point

Maybe I am doing something obviously wrong, but my 15-minutes walking isochrone seems to not contain its starting point:

curl -X POST \

The starting point is indicated by a Marker, and the isochrone is in blue.
Thanks in advance for any clarification!

This might actually be a problem with how Folium is plotting the isochrones polygon, now that I think about it. However, it seems unlikely to be a projection problem, because it’s plotting the Marker correctly.

Hi @alberto-santini,

You are currently searching an isochrone in somalia. You have to pass long,lat coordinates.
I guess folium if folium is taking lat,long coordinates you need to swap before searching and again before rendering the response.
