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.
Create a Graphic passing in a Point and the simple marker symbol as parameters.
Add the graphic to the graphics overlay with graphicsOverlay.getGraphics().add(graphic).
