For this assignment we explored the canvas element in html5 with javascript to create an interactive web page. My code incorporates two draw functions, one to create circles at random sizes and another for the lines.  JQuery maps the mouse’s position to the center of the circles and end point of the lines. while a setInterval function calls the drawing functions at a specified rate in frames per second.  The transparency effect is created using the rgba color mode where an “alpha” or opacity value can be given to the normal rgb color value.
