D3GeoStatic: Static View will draw single-layer geometry shapes such as a state, a continent. You can use your own geojson/topojson to show anything you want.
D3GeoDoubleLayer: Static View will draw double-layer geometry shapes such as a continent. By clicking a country in the continent the view will zoom-in to the specific country and to show provinces. Of course your geojson need to contain the countries and the provinces information*
D3GeoEvents: Events View will draw single-layer or double-layer geometry shapes. The point for this feature is to show event-driven information in a geospatial view such as real-time analytics result visualized on a map as a real-time monitoring dashboard. Please check the demo step below to see some examples with mock-up streaming data. AWS AppSync and AWS IoT can be used in these use cases to feed real-time streaming information to your Vue application - this topic is out of scope and will be provided as another artifact.
D3GeoLeaf: Draw geometry shapes on top of the Leaflet view. Leaflet is an open-source JavaScript library for interactive maps. The use-cases include drawing a road's or subway's geometry shapes with statistical values. Normally used in monitoring dashboard.
