This visualization gallery presents a comprehensive analysis of PDF.js contributor and repository data using multiple interactive D3.js charts. It includes a zoomable bar chart showing total commits by author, a repository commit chart, and a force-directed network graph using `d3.forceSimulation` and `d3.forceManyBody` to display author collaboration patterns. The code also demonstrates stacked bar charts for missing children statistics, choropleth maps using `d3.geoMercator` and `d3.geoPath` for geographical data, and various bar charts with tooltips and hover effects. All visualizations load data from CSV files and use SVG rendering with animations.
