Position of node, or spline control points.
For nodes, the position indicates the center of the node. On output, the coordinates are in points.
pos can be used to set the initial position of a
node. By default, the coordinates are assumed to be in inches. However, the
-s command line flag can be used to specify different
units. As the output coordinates are in points, feeding the output of a graph

is assumed the positions have been set by one of the layout programs, and are
therefore in points. Thus,
neato -n can accept input correctly without
-s flag and, in fact, ignores any such flag.
