Graph drawing and Visualization

Information visualization is a classic topic that has become crucial in our information-heavy digital age – from slick infographics to detailed interactive cartographic maps, they help us visually understand and interpret the world. The subarea of network visualization focusses on applications in which the underlying data set is a graph. Graph drawing has a rich history in computer science, but new challenges are posed by the unprecedented size, dynamic nature, and interactive aspects of present-day graphs.

Graph drawing is, in essence, a geometric operation: abstract vertices and edges need to be turned into concrete points and curves in a two-dimensional plane. We study the fundamental underlying geometric problems that arise in this operation.

Two main challenges need to be addressed. The first challenge is to translate requirements that are specific to certain applications into mathematically quantifiable properties. The second challenge is to design correct and efficient algorithms that satisfy a given set of properties.
