 In this example, at `perplexity` = 25, 100, and 250, we embedded the data 3 times, each with a different random initialization, and we embedded the null data once.  We can then plot any of the embeddings at any of the values of `perplexity` using the `plot_embedding` method shown above.  We can also visualize the entire sweep using the `sweep_boxplot` and `sweep_lineplot` functions, as shown below.

 Using these figures, we can summarize the quality of t-SNE as the `perplexity` hyperparameter is varied.  Using these figures, as shown in our paper, we can determine optimal values for `perplexity` (or `n_neighbors` in UMAP), find characteristic scales and neighborhood sizes for different samples, and detect robust features in embeddings.  We can also determine the optimal `perplexity` for each sample individually and use this `perplexity` to
