This visualization shows the history of D3.js commits, stacked by repository and aggregated into weekly time buckets. The data comes from a JSON file of all D3 commits and is rendered as an SVG area chart with randomly colored layers. Using d3.json for loading, d3.utcWeek for time aggregation, d3.stack and d3.area for the stacked layout, and d3.scaleTime and d3.scaleLinear for axes, the chart fills the full browser viewport.
