AnyChart JS Maps provide callout elements that pull small or overlapping regions into labeled side panels with connector lines, making every area accessible. Combined with map labels and zoom controls, callouts solve the common problem of tiny regions on choropleth maps.
This sample renders a US choropleth of state areas in square kilometers, colored with a six-range ordinal scale. Two callout groups highlight compact states: one on the left for states under 50,000 km² (VT, NH, MA, RI, CT, NJ, DE, MD, HI) and one along the top for states between 50,000 and 100,000 km². Each state shows its ID label, and HTML tooltips display the area value.
See the AnyChart Maps documentation for all configuration options.
