EarthChart plots (longitude, latitude) points on a background image of the earth. Assign the X series to a column containing longitude, and assign a marker series to a column containing latitude values.
Anything that works for a ScatterChart will also work for EarthCharts. EarthChart also supports additional keywords for image generation.
Use MASK for an image with masked continents. Continents will be filled with the MASK color, and oceans with the FRAMECOLOR:
