Support is lacking in the area of providing the ability to encode data with sizes or symbology except for the case of circle markers. You create a Leaflet map with these basic steps: Create a map widget by calling leaflet (). With addTiles you will add the default base map and with setView you will be able to set a center point and a zoom level. Print the map widget to display it. Add layers (i.e., features) to the map by using layer functions (e.g. addTiles, addMarkers , addPolygons) to modify the map widget.
