You can set each annotation type property to "text", "image", or "custom". In this demo, annotation type has been set to "custom".
Custom annotations require that you specify your own display template in SVG format. As you can see in the demo code, you can access annotation data within template markup.
For more information on annotation settings, refer to the annotations[] help topic.
