How to plot a graph with geographic coordinates

Hi,

I need to draw a graph where the nodes have a geographic coordinates; i know that the function "gplot" allow you to draw a graph once you give the coordinates of the nodes and adjacency matrix, but it works only in cartesian coordinate system; is it possible to do something similar but with latitute and longitude as coordinates?

While "gplot" works for cartesian coordinates, MATLAB provides functions specifically designed for geographic data.

"geoplot" allows you to plot lines or markers on a map based on latitude and longitude coordinates. To do so,

1. Define your latitude and longitude vectors ("lat" and "lon").
2. Create the adjacency matrix representing your graph connections.
3. Use "geoplot(lat, lon)" to plot the nodes as markers on a map.
