DESCRIPTION
An area chart is a line chart whose series are filled down to the baseline, in block characters placed to an eighth of a cell, translucent so that overlapping areas show through each other: 0.6 of the color over the background, 0.8 when the areas are stacked. With stacked the areas lie on each other and show how parts add up to a whole; stacked => 'percent' shows the shares. The y axis includes zero, where the areas grow from.
An area has no line along its top by default; line => 1 adds one in Braille dots. fill_opacity sets the translucency, curve the shape of the top. Everything else is described on Term::Fabulous::Widget::XYChart; an AreaChart is an XYChart whose series are area series unless they say otherwise.
