Bubble Markers
Documentation
This example demonstrates how you can flag specific locations on the VectorMap using markers of the «bubble» type. Marker size depends upon the attribute specified by the dataField property.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
