Add / display markers at specific locations / positions (Unfolding map) with processing

[kkxxbdm]

Hi, I was wondering, how to add / display markers at specific locations / positions? I tried a specific example, and it seems that it does not work. Could anyone please let me know what might be wrong in the code?

using the example
Unfolding Maps / MarkerSelectionApp/
on a Raspberry Pi works.

possibly same problem as with your other question,
your code use

size(1000,1000);

instead P2D like above mentioned example
