Unfolding has a GPXReader with very basic functionality.

Example:

> Hello @Ciosiek , This example uses Processing 4.3 library and Unfolding 0.9.92 library and worked in Visual Studio Code 1.88.1: import processing.core.\*; import java.util.List; import de.fhpotsdam.unfolding.UnfoldingMap; import de.fhpotsdam.unfolding.data.Feature; //import de.fhpotsdam.unfolding.geo.Location; import de.fhpotsdam.unfolding.marker.Marker; import de.fhpotsdam.unfolding.utils.MapUtils; import de.fhpotsdam.unfolding.data.GPXReader; //GPX Reader public class App extends PApplet {…

I was also able to write my own custom code from the _GPXReader_ source example and custom parse the JSON files which gave me much more flexibility.

You can also load the GPX files with _loadStrings()_ and parse these for the data you want and plot the tracks.
