Feature request,

Thank you @emonson, for the visualization.

I really like it, and it is a good tool to visualize the terms.

I was wondering how can we add the sentiment or text label on the right of the image?
Or put a color on the image according to the sentiment, so the heatmap with negative sentiment can be red and the one with positive can be green?

I am still hacking on it, but If you have a hint let me know.
