Modules
Fude (筆, "brush") draws charts in a Phoenix app.
A note on a chart, at a place of its data: what a graphics desk writes on a chart to tell its story.
What a channel of a chart shows: the field of the data it reads, and
how. x, y, color and size are channels.
A chart: its layers, its words (title, subtitle, caption, source), and the data it draws.
The function component of Fude: <.chart>.
The data of a chart, in columns: each field with its type and its values, in the order of the rows.
Collaboration on charts, for people and agents, in
Issho's rooms: a chart's spec is a
shared state of the room (Issho.State), that everyone changes with
the same functions, and that is a valid chart after every change.
A place in a chart, in the chart's own terms (its data, never pixels,
as each person has the chart at their own size): where a person's
pointer is, where an agent points (Issho's point tool). Its format is
part of Fude's public API, and only grows.
One layer of a chart: a kind (:bar, :line...), its channels and its
options. A chart has one layer, or several drawn one over the other
(Fude.layers/2).
New points for a chart on the page, without sending its data again.
A chart's data from an Ecto query, grouped and aggregated in the database: a chart of fifty million rows reads a few hundred.
The rules of a chart's scales that the server and the browser both apply: nice domains, the ticks of a number axis and of a time axis, the bins of a histogram and the units of a time.
A chart as plain data, to save and load back.
Helpers for testing charts with Phoenix.LiveViewTest: they read what a
chart shows, as the server made it for the browser.
