Survey results in the raw can be useful, but for some projects it can be helpful to see the connection between how each user answers multiple questions. Let’s imagine we asked a group of people two questions about breakfast options, how much they like eggs and how much they like ham. It’s easy to make a bar chart for how many people like/hate each breakfast food, but these questions are hard unless you have another approach, like the alluvial diagrams discussed in this post:
Do people who like eggs also like ham?
Do people who like eggs hate ham? (or vice versa)
