Unable to view countries on worldmap using JSON API as datasource

I have a json api
I get response as below from the above request.
[{“key”:“US”,“latitude”:44.29048647,“longitude”:-93.26801274,“name”:“United States of America”},{“key”:“AU”,“latitude”:-33.42004148,“longitude”:151.3000048,“name”:“Australia”},{“key”:“IN”,“latitude”:15.491997,“longitude”:73.81800065,“name”:“India”}]

I’m not able to display these counties in the map.
Please help.

Worldmap panel is deprecated (so it has very likely som bugs). Try to use geomap panel instead + suitable datasource for json api data.
