Write a program that displays a 500 x 500 pixel graphics window. Display a message at the top of the graphics window inviting the user to click a point on a (as yet non-existent) circle. After the user clicks the mouse, ask them to click a point on the opposite side of the circle. Draw a circle that passes through these two points and whose center is midway between them. Color the circle’s interior red. Now, repeat the following steps five times: ask the user to click a new point (again, display this prompt at the top of the graphics window) and then move the circle so that its center is at this new point.
