Maybe I’m just tired but those graphs are extraordinarily confusing.
I was confused too, but I think I figured it out. The x axis is how you feel, with the right side being ‘very positive’ and the left being ‘very negative’. If a lot of people really love n group, then there would be a tall spike on the right side, if a lot of people disliked that group, the spike would be on the left. If very few people liked that group, the spike on the right would be much smaller. You were probably joking though.
I wasn’t joking, I couldn’t figure it out. Granted I didn’t spend a lot of time on it, though.
