Color document boundaries (or classes) in dispersion plot

[rebeccabilbro]

Describe the solution you'd like I work with text data a lot and am very excited about the new DispersionPlots! As a future feature, it would be very useful to indicate document boundaries on the plot using a high perceptual contrast colormap, or perhaps a qualitative colormap to color the classes (when classes are available).

Use case Adding document boundaries (or per-class document coloring) to the plot would enable me to visualize things like:

• n-grams that are very common in only a particular subset of the documents
• n-grams that are very common across all documents
• n-gram appearance vs. variance in document length
• n-gram appearance on a per-class basis (if classes are available)

@lwgray on August 24th, 2018 Issue #576 Doesn't completely resolve this issue thus it will remain open. However, #576 does add document boundaries to the dispersion plot
