I published a new tutorial for D3 earlier this year: https://observablehq.com/@d3/learn-d3

Thanks.

Is there anything in it that is now outdated?

It would be nice to mention the D3 version targeted in the very first paragraph.

This tutorial, along with the hundreds of other examples we maintain on Observable, are kept up-to-date with all D3 releases.
