Point (dot) maps place markers at geographic coordinates to show where specific items or events are located. They are ideal for visualizing discrete locations on any world or regional map.
This sample visualizes shipping ports worldwide on a dark-themed world map, with five marker series color-coded by outflow volume — from under 100,000 to over 10,000,000. A legend identifies each bracket, HTML tooltips show port name, country, and outflow count, and zoom controls allow closer exploration of dense coastal areas.
