On the Recognition of Outerplanar Graphs with Queue Number 1

Michael A. Bekos, Thomas Depian, Stefan Felsner +7

A linear layout of a graph is defined as a total order of the vertices and a partition of the edges to pages. In a stack (queue) layout, no two edges on the same page may cross (ne…

On the Complexity of Extending Storylines

Alexander Dobler, Siddharth Gupta, Philipp Kindermann +2

Storyline layouts visualize temporal interactions by drawing each character as an x-monotone curve and enforcing that the participants of every meeting form a contiguous vertical g…

Collaborative Problem Solving in Mixed Reality: A Study on Visual Graph Analysis

Dimitar Garkov, Tommaso Piselli, Emilio Di Giacomo +4

Problem solving is a composite cognitive process, invoking a number of cognitive mechanisms, such as perception and memory. Individuals may form collectives to solve a given proble…

Graph Drawing for LLMs: An Empirical Evaluation

Walter Didimo, Fabrizio Montecchiani, Tommaso Piselli

Our work contributes to the fast-growing literature on the use of Large Language Models (LLMs) to perform graph-related tasks. In particular, we focus on usage scenarios that rely…

Geometric realizations of dichotomous ordinal graphs

Patrizio Angelini, Sabine Cornelsen, Carolina Haase +5

A dichotomous ordinal graph consists of an undirected graph with a partition of the edges into short and long edges. A geometric realization of a dichotomous ordinal graph in a…
