I see d3 imported alongside stardust in this example: https://stardustjs.github.io/examples/daily-activities/ https://stardustjs.github.io/examples/daily-activities/ Edit: from their paper: "We see Stardust as a complement to D3 instead of a replacement. Stardust is good at rendering a large number of marks and animate them with parameters, while D3 has better support for fine-grained control and styling on a small number of items. For example, to create a scatterplot with a large number of items, we can use D3 to render its axes and handle interactions such as range selections, and use Stardust to render and animate the points"
