An L-shape is the union of a horizontal and a vertical segment with a common endpoint. These come in four rotations: , , and . A k-bend path is a simple path in the plane, whose direction changes k times from horizontal to vertical. If a graph admits an intersection representation in which every vertex is represented by an , an or , a k-bend path, or a segment, then this graph is called an {}-graph, {,}-graph, Bk-VPG-graph or SEG-graph, respectively. Motivated by a theorem of Middendorf and Pfeiffer (1992), stating that every {,}-graph is a SEG-graph, we investigate several known subclasses of SEG-graphs and show that they are {}-graphs, or Bk-VPG-graphs for some small constant k. We show that all planar 3-trees, all line graphs of planar graphs, and all full subdivisions of planar graphs are {}-graphs. Furthermore we show that complements of planar graphs are B17-VPG-graphs and complements of full subdivisions are B2-VPG-graphs. Here a full subdivision is a graph in which each edge is subdivided at least once.
