Generated by in-browser Javascript. Using SVG's viewBox attribute to pan/zoom to show the whole extend of the wire paths, while keeping the size of the final SVG managable. The widths of the strokes of the wires and size of the crossing point highlights are calculated off the zoom factor to stay relatively the same size, regardless of how much area the wire paths take.

Origin is the green dot, and each wire crossing point has a yellow highlight around it.
