  "Description": "Diagnostic plots for optimisation, with a focus on\nprojection pursuit. These show paths the optimiser takes in the\nhigh-dimensional space in multiple ways: by reducing the\ndimension using principal component analysis, and also using\nthe tour to show the path on the high-dimensional space.\nSeveral botanical colour palettes are included, reflecting the\nname of the package. A paper describing the methodology can be\nfound at\n<https://journal.r-project.org/articles/RJ-2021-105/index.html>.",
