This call for participation is for the Visual Software Analytics research group from Leipzig University, which is participating in the Google Summer of Code program. The group is looking for independent participants to work on various projects related to graph-based software analytics and visualization, with a focus on open-source development using tools like Neo4j, A-Frame, and Unity. Participants will receive a scholarship of $5,000 and have three months to complete their project, with the option to work on hardware such as HTC Vive or Oculus Rift. The projects range from classic software development to designing virtual reality applications, and participants can choose from a variety of tasks and mentors, including those working on jQAssistant and Getaviz.
