I have a data set that keeps track of who referred someone to a program, and includes the geo coordinates of both parties for each record.
What will be the best way to visualize this kind of data set? This visualization should also be able to use the geo coordinates to place this entities in the map to form clusters, or to superimpose them on a real map.
I am interested in an algorithm and/or a library that will help me do this. Library should be preferably written in Java, Python, Scala, or NodeJS. The record count can be as big as a thousand or hundreds of thousands.
