I'm a visual learner, so I love a good graph. I find them to be the best way to simply get across a complicated idea. Well, most of the time I think that.
Sometimes the people who make graphs don't share my passion and end up making something that is just confusing. For example, don't use a pie graph to show progression. You are an adult. You should know that.
I think seeing a bad graph is like seeing a dolphin on fire. I can't even imagine what events led here but I am still very angry and upset at the outcome. Don't need a graph to show that.
