The product structure of squaregraphs
Abstract A squaregraph is a plane graph in which each internal face is a 4‐cycle and each internal vertex has degree at least 4. This paper proves that every squaregraph is isomorphic to a subgraph of the semistrong product of an outerplanar graph and a path.

FOG: Finding outerplanar graphs [PDF]
In this demo we will present FOG, a system that mines frequent outerplanar graphs. We argue that outerplanar graphs are an interesting class as they can be mined efficiently and are practically relevant for chemical applications.

On the Planarity of Generalized Line Graphs
One of the most familiar derived graphs is the line graph. The line graph $L(G)$ of a graph $G$ is that graph whose vertices are the edges of $G$ where two vertices of $L(G)$ are adjacent if the corresponding edges are adjacent in~$G$.

Improved Bounds for Track Numbers of Planar Graphs
A track layout of a graph consists of a vertex coloring and a total order of each color class, such that no two edges cross between any two color classes.

k-colored Point-set Embeddability of Outerplanar Graphs
This paper addresses the problem of designing drawing algorithms that receive as input a planar graph G, a partitioning of the vertices of G into k different semantic categories V0,…, Vk−1, and k disjoint sets S0, …, Sk−1 of points in the plane with |Vi|=

Maximal outerplanar graphs as chordal graphs, path-neighborhood graphs, and triangle graphs [PDF]
Maximal outerplanar graphs are characterized using three different classes of graphs. A path-neighborhood graph is a connected graph in which every neighborhood induces a path. The triangle graph $T(G)$ has the triangles of the graph $G$ as its vertices,
