So, I want to plot this locus.

This site says it has 4400 data points.

"This data set gives wavelengths every 1.0 nm, along with the associated 
CIE xyz values for the spectral locus of the 1931 CIE chromaticity 
diagram. They are called xyz values here as they are called that in the 
original source, but they are also known as xyY or XYZ values."

https://rdrr.io/cran/SpecHelpers/man/CIExyz.html

I can't figure out how to download them from that site, however. Is 
there another source I can get them from?

Also, I'm guessing the data set will allow me to plot a bunch of points, 
which is great. But how do I create a smooth surface from those points?

Thanks!


Mike
