This CL updates the d3.js library to version 5.4. The most notable
change is that the library can now distinguish between click and drag
events if an element supports both selection via click and displacement
via drag.

Curiously, npm created a 'package-lock.json', which is ~500 lines, and
which is supposed to be checked into the repository according to documentation.
