A plain-language introduction to a kind of chart, shown in the description
dialog's collapsible "About this chart type" section.
The rest of the dialog assumes the reader already knows what the chart type
is. A reader who has never seen one -- which, for someone blind from birth,
may be most of them -- is told a name like "Violin Plot" and nothing else,
so each type also says what it is, what it is for, and what it looks like.
