Hi Daniel,
Thanks for contacting Syncfusion support.
In Syncfusion Dashboard, we support shapefile in JSON format to render it in built-in Map widget. Please find the shape JSON of “States of Mexico” in the below. We can add this shape json as Custom Map in Map widget. Please refer the below UG link to add custom map in Syncfusion Dashboard.
Please let us know, if you need any further assistance.
Regards,
Renuka N.
