Add a box for shape to graph builder

[shampton82]

I'd like to add a suggestion that there be a box for "shape" added to graph builder.  that way you can change the shape of your markers based upon the column added to that box.  This would be similar to the option in rows to color or mark by column but would be locally done just in graph builder.

This might not be quite as automatic as it could be, but you can drag the category to overlay and then change the marker for each category level.

With Jmp18, it got easier - use Overlay Encoding -> Style to automatically use marker shapes instead of colors:
