Notes
:
This applet does not work in IE8 but should work in other browsers.
Use the blue squares on the movable line to change slope, intercept.
Right now pasted data must have variable names (use single words, no symbols)
Dotplot coloring may not exactly match count, as coloring is based on bin mid-points
