GitTruck@Duck - Interactive Time Range Selection in Hierarchy-Oriented Polymetric Visualization of Git Repository Evolution

In this work, we present GitTruck@Duck; a web-powered software visualization tool that combines hierarchical file structure with configurable software evolution and collab-oration metrics on adjustable time ranges. In an automated mining process, Git Truck aggregates a system's Git history using an in-memory relational database, along with an algorithm for detecting the renaming of files over time. Users can explore the Git history in a 2D hierarchical visualization of folders and files, where they encode evolution and collaboration metrics (e.g., top contributors or last change date) on the size and color of the marks that represent files. Users can gain fine-grain control over these metrics by specifying the time ranges for inspection.
