Hi Sue,
Greetings from Syncfusion. The JSON file that you have shared contains
latitude and longitude values like -831.705561876297, 40.27778428281337
but the actual latitude ranges from -90 to 90 and the actual longitude ranges
from -180 to 180. We assume that you have used the latitude and longitude based
on the continuous map shape support. We suggest you convert that
values into JSON properly. Kindly get back to us if you have further queries.
Thanks,
