To draw a rectangle on a screen, you need the <rect> element with 6 attributes to control the position and shape:

• The x defines the horizontal position of the top left corner of the rectangle

• The y defines the vertical position of the top left corner of the rectangle

• The width attribute sets the width of the rectangle

• The height attribute sets the height of the rectangle

• The rx and ry attributes define the horizontal and vertical radius of the rounded corners. If you omit them, they default to 0
