Visualizing the digits dataset using UMAP

  run this example as a notebook — or grab the .ipynb (also linked at the bottom of the page)

This example loads in some data from the scikit-learn digits dataset and plots it using UMAP, with one color per digit class and a legend mapping colors to digits.
