How to visualize the umap of dataset(over 50000 cells) better?

[xiaozhongshen]

Hi! Can I ask a question about how to visualize the plot better? When I used the code on https://omicverse.readthedocs.io/en/latest/Tutorials-plotting/t_visualize_single/#optimizing-color-mapping, I found it's diffcult to see the legend and the umap of a large dataset both well in a plot, please help me to improve that.
