Description: Diagnostic plots for optimisation, with a focus on
        projection pursuit. These show paths the optimiser takes in the
        high-dimensional space in multiple ways: by reducing the
        dimension using principal component analysis, and also using
        the tour to show the path on the high-dimensional space.
        Several botanical colour palettes are included, reflecting the
        name of the package. A paper describing the methodology can be
        found at
