-Using Javascript, make a program within Processing that randomly selects coordinates for 4 points within the size of the Processing display window. Draw a red circle around each point with a radius of at least 5 pixels. Then, draw a spline curve between two of the points. HINT: use the size() function, the width and height variables, and the random() function.

-Now using the same program, modify it in two ways: (1) when the mouse is pressed on any point, that point changes color (e.i. turns to green); and (2) when the user presses on any key, the program toggles between drawing a black curved line on a white background and drawing a white curved line on a black background.
