Plotting Maps with Cartopy and Features

This function uses the Cartopy library to plot a map and adds features such as coastlines, land, oceans, and state boundaries. It also allows for plotting specified longitude and latitude points on the map.

Technology Stack : Cartopy, Numpy, Matplotlib

Code Type : Map drawing
