* A great example is the Mona Lisa color histogram, which now works in multitouch (https://observablehq.com/@d3/mona-lisa-histogram) * Multitouch and the new event system are documented in the forthcoming “multitouch done right” (sic) https://observablehq.com/d/8c6133113d33b60c * Another goodness of D3 6.0 is documented in the forthcoming "d3.groups and d3.hierarchy" https://observablehq.com/d/9a453665f405eebf * d3-Delaunay is another highlight; https://observablehq.com/d/58f6cc721fa26757 is a new notebook that can demonstrate it in a simple but colorful way

I’ve trimmed and bolded the next cell facilitate faster scanning and added more links to examples.
