	{map}	The field with the number - else the first numeric field.
	{sparkline}	The field with the number - else the first numeric field.
	{textarea}	The text before anything was sent, escaped.
varied	{lorem}	Bare option: leave the classic opening "Lorem ipsum dolor sit amet" out - for the second text on a page.
vary	{cache}	Whatever else the rendering depends on: vary=$userId keeps a copy per user, vary=$country one per country.
vertical	{timeline}	Bare option: dates on the left and cards on the right, one under the other - for a long list.

words	{excerpt}	The length in words, default 40. A text no longer than that stays whole.
	{lorem}	So many words exactly, as sentences; fewer than five are a title, without a full stop. 50 when no length is given.
x	{chart}	Scatter, bubble, heatmap: the field of the horizontal axis (heatmap: the columns).
