3D Plot in Chapter 5 not rendering #83
Description
Nothing I do seems to affect the 3D scatter plot in chapter 5. Something is failing silently...?
It's saved in source/img/classification1/, so it persists between builds even if the build fails. So it still looks OK (but the colours are wrong in the plot -- malignant is a light blue (in the rest of the chp it is orange)).
I'm moving on -- this is important to fix at some point, but doesn't need to be fixed for the first run of the course.
