This gallery entry presents a network analysis of PDF.js contributors, showing a radial graph that connects the central repository to its contributors and related projects. The visualization combines an animated D3 force simulation with multiple chart types, including bar charts of commit counts per author and repository, and a grouped bar chart analyzing complaints and FIR data from CSV files. The code uses D3 v7 APIs such as `d3.rollups`, `d3.zoom`, `d3.forceSimulation`, and `d3.scaleBand` to create interactive, zoomable charts with tooltips and hover effects.
