Show a simple marker symbol on a map.

Use case
Customize the appearance of a point suitable for the data. For example, a point on the map styled with a circle could represent a drilled borehole location, whereas a cross could represent the location of an old coal mine shaft.
How to use the sample
The sample loads with a predefined simple marker symbol, set as a red circle.
How it works
- Create a
SimpleMarkerSymbol(SimpleMarkerSymbolStyle, color, size). - Create a
Graphicpassing in aPointand the simple marker symbol as parameters. - Add the graphic to the graphics overlay with
graphicsOverlay::graphics()::append(graphic).
Relevant API
- Graphic
- GraphicsOverlay
- Point
