GitVis3D

GitVis3D is a visualization tool for git communities. This tool visualizes a versioning graph that consists of contribution edges and update edges as 3D animation in which new nodes and edges are added to the scene over time.

The basic idea of the visualizing method of the versioning graph in 3D space is shown as follows:

This tool also contains a funciton that automatically creates a versioning graph from commit logs retrieved from the GitHub repository via GitHub API. To reduce the number of requests sent to the GitHub API, the created versioning graph is stored in the Neo4j graph database.
