Colophon

Running text is set in Source Serif 4; headings, notes, captions and the dials are set in Instrument Sans. Mathematics is typeset with KaTeX. Running text is held to a measure of about sixty-five characters, set solid with indented paragraphs, and laid out in pages rather than one long scroll.

The layout takes its working margin from Edward Tufte’s books. The right margin holds the author’s notes, figure captions and the dials for each figure. The left margin is kept empty for the reader.

The figures are drawn by hand in SVG, with no charting library. Each one generates its data from a seed, so a link reproduces exactly what you saw, down to the page.

To turn: →, space or page down to go forward; ←, shift-space or page up to go back; home and end for the first and last page. A swipe, the scroll wheel, or a click beside the page also turns. Numbers in blue in the text can be dragged, or focused and moved with the arrow keys; hold shift for larger steps.
