Hanan grid

In geometry, the Hanan grid $H (S)$ of a finite set $S$ of points in the plane is obtained by constructing vertical and horizontal lines through each point in $S$ .

The main motivation for studying the Hanan grid stems from the fact that it is known to contain a minimum length rectilinear Steiner tree for $S$ .^[1] It is named after Maurice Hanan, who was first^[2] to investigate the rectilinear Steiner minimum tree and introduced this graph.^[3]
