Fork of D3 Git History Streamgraph
This streamgraph visualizes the commit history of the D3.js repository ecosystem, with each colored layer representing a different D3 package. The thickness of each layer corresponds to the number of commits per week, smoothed using the `array-blur` library. Layer order follows the time of each repository's first commit, revealing the monolithic `d3` repo's early development, a burst of package creation around the 4.0 release in 2014, and subsequent maintenance activity. Built with D3 6.5.0, it loads commit data from a JSON file and uses SVG rendering with `area` generators for the streamgraph shapes, and `scaleOrdinal` with HCL colors for the layers.
AI-generated descriptionThis is an experiment in visualizing D3 Git History. Each layer is a D3 repository. The thickness of each layer is the number of commits per week with smoothing applied. This visualization uses a modified Streamgraph technique where the layer order is determined by the time of the first commit. So, as you read the labels from bottom to top, that corresponds to the history of when each repository was introduced.
On the whole, one can see that development occurred in the original monolithic d3 repository from late 2010 to mid 2014. In late 2014 we see an explosion of packages, corresponding to the 4.0 release of D3. Since that great explosion, we see a big push on d3-delaunay in 2018, and ongoing development/maintenance work pretty evenly distributed across the various D3 packages.
