Recipes

Whole solutions to the things people actually build, rather than options in isolation. Each one runs on this page.

Synchronised charts	two charts, one pointer and one range — and the feedback loop you have to break
Load history on scroll	the unclamped logical range, put to work
A live streaming chart	a socket, a forming candle, and a "go to now" button
A sparkline	the smallest useful chart, for a table of thirty
Downloading the chart	a PNG of what is on screen, and the numbers behind it as a CSV
A chart an agent can read	the chart in words, and a model's answer drawn back onto it
