marvellous!!! is there a control to "zoom out" sometimes part of the trajectories are overflowing to the sides.

i found it ! thanks! Bourke's shapes are amazing

Is there a way to include the paths in the SVG export option?

Apologies, but not directly, no. You would have to take a screenshot. For performance and in order to get the layering of overlapping trajectories correct, the axes are in SVG but the paths are drawn with WebGL.
