Abstract

This report describes the challenges and winners of the 2026 Graph Drawing Contest, held in conjunction with the 34th International Symposium on Graph Drawing and Network Visualization (GD'26) at Brock University in St. Catharines, Ontario, Canada. The mission of the Graph Drawing Contest is to monitor and challenge the current state of the art in graph-drawing technology. This year’s edition featured two categories: a creative topic in which participants visualized voting patterns across the years of the Eurovision Song Contest, and a live challenge held at the conference, where participants had to produce straight-line drawings of graphs on a grid that were k-plane for as low a value of k as possible. The creative topic focused in particular on revealing patterns in how countries vote for one another over time, using a dynamic and multivariate dataset containing both jury and public votes.
