You have learned about several different marker types that still look like your typical marker. In this section, you will learn how to add markers that create a pie and bar chart—not exactly your standard marker.
The Leaflet Data Visualization Framework plugin allows you to create markers that are just shapes: a standard pin style marker with a shape cutout, a star marker, and a polygon marker. It also allows you to add pie chart and bar chart markers to your map.
The Leaflet Data Visualization Framework plugin also has markers for radial bar charts, coxcomb charts, stacked and radial meter markers, as well as a data layer, choropleth layer, and a legend control. This is a plugin worth exploring. You can download it at http://humangeo.github.io/leaflet-dvf/.
