The coordinates start from 0,0, the top-lefthand corner of the image. rects are rectangles with the top-left and bottom-right corners at the two x,y positions shown. points are points at the x,y position. polys are polygons with between 3 and 100 corners at the x,ys shown. circles have their center at the first x,y — the second is a point on the circle. The point nearest to the cursor is returned; otherwise, the closed figure that encloses the cursor is not returned. As it stands only the rects are left uncommented. They set up two areas in the left and right halves of the image and designate the files left.html and right.html to be returned if the mouse click occurs in the corresponding rectangle. Notice that the points are expressed as x,y <whitespace>. If you click in the left rectangle, the URL www.butterthlies.com/left.html is accessed, and you see the message:

You like to sit on the left

and conversely for clicks on the right side. In a real application, these files would be menus leading in different directions; here they are simple text files:
