rectangle
rectangle(x0, y0, x1, y1)Input: x0, y0, x1, y1 · Output: no output
What it is
Draws an axis-aligned rectangle. x0 and y0 (numbers, data units) are one corner; x1 and y1 (numbers, data units) are the corner diagonally opposite it, and which of the two you give first does not matter. rect is a plain alias.

Examples
From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.
# A square canvas, so that equal ranges really are equal scales and the
# circle below comes out round. Without it the figure would render an
# ellipse while the paragraph above it explained how to avoid one.
