dotsFigurefunction

A constellation laid out as numbered dots on a page widthMm by heightMm: the stars placed by a stereographic chart, east to the left as in the sky, made as large as fits; the dots sized by brightness and never more than a third of the distance to the nearest dot (DOT_LIMITS), and two stars too close for the smallest dots moved apart to the distance they need; every visit numbered along the lines in drawing order (one number for each time the pencil reaches a star, a star met again carrying both numbers); each number put where it touches no dot, line or other number.
