3D plot from a 2d array for PCA

  1. Given that the input X is 2D, but the resulting plot is in 3D, how was this transformation achieved?
  2. What does deb.update_layout(yaxis2 = dict(title_text = ‘test’, visible=True)) do where is the title_text printed here in the plot?

On the File->Open are all the helper files for this Lab, you better check there what those 2 functions are doing to obtain those results!
