Default Shunted Potentiometer Calculator - Responsive, real-time graphing

I put together this calculator as an experiment in HTML canvas programming.

The interface and implementation still have some quirks, e.g. allowing you to choose combinations of mutually-exclusive options, or failing with a division-by-zero, or functions going out-of-domain. I figured I'd post it in an attempt to get suggestions or find out glaring flaws before polishing it.

Shunted Potentiometer Calculator - Responsive, real-time graphing
I tried it but I'm not too clear on what it represents. it need a legend/explanation as to which resistor is which. I would like to see the effect on accuracy since I have a 10 turn pot with a load resistance and how much a shunt pullup can linearize it. Not knowing what is what leaves me unsure what its showing me. It does seems to work. My application is a 1K pot with a 10K load and a 10K from input to wiper.

I've written a pot tapering spreadsheet and, without running a bunch of comparison cases, I have no idea what this does; you need to describe how to use it.
