Annotations are containers for images, text blocks, and custom content. By using annotations, you can display additional information to your end users and improve the readability of data visualized within your app.
To create annotations, populate the VectorMap's annotations array. Each object in the array configures an individual annotation. To specify settings for all annotations, use the commonAnnotationSettings object. Individual settings take precedence over common settings.
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.
