Graphics overlay (dictionary renderer)

This sample demonstrates applying a dictionary renderer to graphics, in order to display military symbology without the need for a feature table.

Use case

Use a dictionary renderer on a graphics overlay to display more transient data, such as military messages coming through a local tactical network.

How to use the sample

Pan and zoom to explore military symbols on the map.

How it works

1. Create a new DictionarySymbolStyle(dictionaryPath).
2. Create a new DictionaryRenderer(symbolDictionary).
3. Create a new GraphicsOverlay
4. Set the dictionary renderer to the graphics overlay.
5. Parse through the XML and create a graphic for each element.
6. Use the _wkid key to get the geometry's spatial reference.
7. Use the _control_points key to get the geometry's shape.
8. Create a geometry using the shape and spatial reference from above.
9. Create a Graphic for each attribute, utilizing it's defined geometry.
10. Add the graphic to the graphics overlay.
