This visualization gallery explores Git commit data from the Mozilla pdf.js project and related repositories. A network diagram uses circles positioned in a ring to represent authors, with circle size proportional to total commit count and connecting lines showing collaboration on shared repositories. The visualization also includes bar charts for commit totals by author and repository, rendered with SVG. The charts use D3.js v7 features such as `d3.rollups` for data aggregation, `d3.zoom()` for interactive scaling, and `d3.select().join()` for efficient element creation. Hover interactions trigger tooltips displaying specific commit details.
