hebasailem/PhenoPlot ? reverse-engineered prompt

Build me a MATLAB toolbox called PhenoPlot that lets me visualize high dimensional data with a glyph style display, where each sample can show up to 21 different variables at once. I want a simple GUI so I can load a CSV or MAT file, pick the columns I want to plot, and generate the PhenoPlot view without having to code everything by hand.

The app should be useful for cellular imaging data, but it should also work with any numerical dataset. Please include a few example files so I can try it right away, plus a couple of demo scripts that show how to make plots from clustered data and from PCA style data. If you need to, look up current MATLAB GUI and export handling docs online so the app works cleanly. Make the plots polished and readable, with legends and export to image or PDF if possible.
