Zusammenfassung

It is well known that any graph admits a crossing-free straight-line drawing in  \$\$\backslashmathbb \R\ ^3\$\$ and that any planar graph admits the same even in  \$\$\backslashmathbb \R\ ^2\$\$ . For a graph G and \$\$d \backslashin \backslash\2,3\backslash\\$\$ , let \$\$\backslashrho ^1\_d(G)\$\$ denote the minimum number of lines in \$\$\backslashmathbb \R\ ^d\$\$ that together can cover all edges of a drawing of G. For \$\$d=2\$\$ , G must be planar. We investigate the complexity of computing these parameters and obtain the following hardness and algorithmic results.
