Layout Project
Graph layout algorithms are widely used to have computers generate visualizations of graph-like information. To that end, a graph layout algorithm generates a two-dimensional layout that consists of positioning data for nodes (represented as closed shapes) and routing data for edges (represented as curves). There are several approaches for designing graph layout algorithms [1,2].
As a participant of this practical, you will work together with other students in order to extend specific layout algorithms or design visualizations using the Java programming language.
The algorithms will be implemented according to the layout interface of the ELK and KIELER projects, which is based on the Eclipse platform. The results may be published as part of either of the two open source projects.

Responsible for this project is Ulf Rüegg. If you need assistance, feel free to send an email or ask for an appointment.
