   The Bourgain Project — the figure on the front page.

   Companion to subjects-plot.js. Everything is drawn in the page's own
   inks and its own face: the dots are black, the rules are the page's
   hairlines, and the one colour — the link blue — marks only the paper
   under the pointer. No series has a colour, because the rows are named.
