This video shows how to use the MXML syntax and the graphics package in Flash Builder 4 to create a rectangle using the new Spark graphic packages. This is part of the new fx package for declarative graphics. You can use Rect or Ellipse to make most shapes. A circle is a specialized type of ellipse with a constant radius, a line is a Rect with a very small value for one of the thicknesses, and a square is a Rect with 4 equal sides.
