Fork of D3 Git History Streamgraph
This streamgraph visualizes weekly commit counts for repositories in the D3 ecosystem, with each layer representing a separate D3 package. Layer order reflects when each repository first appeared, showing the original monolithic D3 development from 2010 to 2014, followed by the 4.0 package explosion and later ongoing maintenance. The visualization applies smoothing via `array-blur` and arranges layers using `stackOffsetWiggle` and `stackOrderAppearance`. Labels are placed using `d3-area-label`. Interactive links connect each layer to the corresponding GitHub repository.
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.
