Thomassen[1] proved that plane cubic graphs are area-universal, i.e., for a plane cubic graph G with prescribed face areas there exists a stright-line (re-)drawing G’ that realizes these areas. Thomassen uses induction and proves the existence of a degenerate drawing where distinct vertices may be placed at the same position. We show that the plane cubic graphs are area-universal using the air-pressure method. In [2,3], a similar method has been applied in the context of area-universality of rectangular layouts. With the poster, we give the idea of how the method can be adapted for other classes of plane graphs, in particular for plane cubic graphs.
