I've looked @ https://github.com/d3/d3/wiki/Tutorials and found there the following sentence: "Tutorials may not be up-to-date with the latest version 4.0 of D3"
However, the latest version is v7. So I'm confused. From my experience there are quite a few interface changes between v4 and v7. API differences between v3 and v4 are quite substantial. I've succeeded to integrate v7 in my learning project. However, I've used trial-and-error method, which is quite time consuming.
