3. Use different map tiles(like OpenStreetMap, Google Map, Mapbox, bing), and easy to change its tiles.

4. It supports clustering, declustering Mechanism. Also, add a heatmap on the map.

5. Add vector layers on the map like point, circle, polygon, polyline, SVG, canvas, circle marker, path and etc.

6. It supports creating custom control on maps, adding image overlays, video overlays on maps, animate marker showing tooltip.
