  Proceedings of GD2020: This volume contains the papers presented at GD~2020,
the 28th International Symposium on Graph Drawing and Network Visualization,
held on September 18-20, 2020 online. Graph drawing is concerned with the
geometric representation of graphs and constitutes the algorithmic core of
network visualization. Graph drawing and network visualization are motivated by
applications where it is crucial to visually analyse and interact with
relational datasets. Information about the conference series and past symposia
is maintained at http://www.graphdrawing.org. The 2020 edition of the
conference was hosted by University Of British Columbia, with Will Evans as
chair of the Organizing Committee. A total of 251 participants attended the
conference.
