Module plan 

A chart laid out at a size: every mark, axis and label in pixels from the chart’s top-left corner, with no window involved.

Bars sharing a band stack, positive values up and negative down. Lines, areas and points take their series in ascending x, and a missing y breaks a line or area. A channel’s Scale and Sort shape its domain, and its title sits under the bottom axis or over the left one.

Functions

plan

chart laid out at size, its labels line high and as wide as measure says. None for what cannot be drawn: a field the data does not hold, a quantitative field over text, a colour that is not discrete, layers that disagree on which axis is discrete, a layered arc, or a size too small to hold a plot.
