Map - Symbol Series
This sample demonstrates how to create maps and visualize locations of major cities in the igMap control using a geographic symbol series.
This sample uses CTP (Community Technical Preview) features. The API and behavior may change when these features are released with full support.
This sample is designed for a larger screen size.
On mobile, try rotating your screen, view full size, or email to another device.
This map uses custom marker template to fill geographic symbols based on population of cities. Cities with smallest population are rendered as gray circles and cites with more population are displayed as green, orange, or red circles.
