The board, drawn

Coordinates placed by hand, roughly where each province falls in Europe, and
everything else drawn from those and from the adjacency rules. Nothing here
is a picture of anybody's board.

It draws the graph rather than regions, and that was not the first idea. The
first idea was Voronoi cells -- every point belonging to the nearest province
-- which makes a handsome cut-paper board and is wrong. Sixty-five pairs that
border each other in the rules came out with regions that did not touch, and
no amount of moving coordinates fixes it: provinces here interleave. The
Adriatic borders Venice with Trieste between their centres; the Atlantic
borders North Africa around the outside of Spain. Convex cells cannot say
that. A map that shows two regions meeting when the rules say otherwise is
worse than an ugly map -- it is a map that loses you the game.

The tests found three provinces drawn on top of each other and a distance
check of mine that was measuring Europe rather than checking my typing: it
failed fifteen honest placings because oceans are large and Moscow borders
five things. The exact check is that a line exists for every border in the
rules and for no others.

The viewBox is fitted to what is actually drawn. Europe is not rectangular,
and the box the coordinates were typed into left a third of the frame as
empty ocean -- which wastes the one thing this game was given more of than
the others.
