Mental model

An Arrow is a pointer. A line with an arrowhead — point at things, show flow or direction on a diagram.

Stroke controls color and thickness, opacity and rotation set appearance and direction (rotate to point anywhere).

The same interactions from a dashboard script:

// Wind-direction arrow
ws.onMessage((msg) => {
  if (msg.heading !== undefined) widget.setRotation('windArrow', msg.heading);
});

A plain line without an arrowhead.
