Click and drag the mouse to draw a line.
This example demonstrates the use of several built-in variables. mouseX and mouseY store the current mouse position, while the previous mouse position is represented by pmouseX and pmouseY. * This example also shows the use of colorMode with HSB (hue-saturation-brightness), so that the first variable sets the hue.
