Parameters for graphs appear frequently throughout the history of research in this field. They represent very important measures for the properties of graphs and graph drawings, and are often a main criterion for their classification and their aesthetic perception. In this direction, we provide new results for the following graph parameters: – The segment complexity of trees; – the membership of graphs of bounded vertex degree to certain graph classes; – the maximal complete and complete bipartite graphs contained in certain graph classes beyond-planarity; – the crossing number of graphs; – edge densities for outer-gap-planar graphs and for bipartite gap-planar graphs with certain properties; – edge densities and inclusion relationships for 2-layer graphs, as well as characterizations for complete bipartite graphs in the 2-layer setting.
