A multi-faceted dashboard visualizes the contributions of authors to the PDF.js project and related repositories, alongside missing children statistics for Indian states. The network graph uses `d3.forceSimulation` to show connections between authors and repositories, while circle packing with `d3.pack` and stacked bar charts with `d3.stack` display commit counts and demographic data. Bar charts, rendered with `d3.scaleBand` and `d3.scaleLinear`, include zoom capabilities via `d3.zoom` and interactive tooltips on hover, with color scales like `d3.interpolateHcl` and `d3.scaleSequential` enhancing data readability.
