drawing

I was wondering how drawing applications draw the entire time the mouse is down without having empty gaps. What I mean is, for example if the program only drew circles at the mouse's X, y coordinate, then if the mouse went too quicly it would seem like a bunch of little circles rather than a nice continuous line. How can this be done without constantly drawing a short straight line between where the mouse was 0.001 seconds ago and where the mouse now is. Thanks
