One NetworkNode is created per sensor (in sensor-space connectivity) or per source vertex / ROI centroid (in source-space connectivity). The 3D position is filled by ConnectivitySettings::setNodePositions from either a FiffInfo channel set or from a forward solution + a FsSurfaceSet pair, and is used by disp3D to draw the node at the correct anatomical location.

The node also stores the lists of incident edges - separately for the full unthresholded graph and for the thresholded view, and separately for ingoing and outgoing directions - so that graph-theoretic measures (degree, hub-ness, in/out strength) can be computed in O(1) per node once the corresponding Network has been assembled.
