Simple Text Analysis POC
Assuming you have sentences, phrases, or words you’d like to categorize . . . you could do something like this to create a visualization. This one is using CSS but it could be done in any basic word processing software. Setting levels of opacity would allow for multiple-overlapping categorizations.
Playing with font size and the rotation of the paragraph also opens up some doors . . . as does doing different rotations at the sentence level depending on the categorization of the sentence. You could get even more granular with stuff like that using data attributes and CSS.
