Population Pyramids

Today's class was again, pretty boring (no offense Mr. Schick). We talked about Population Pyramids today after the first fifteen minutes we did nothing, so I read. And when we started to get into population pyramids, I'm sitting there going, why do we need so many different charts to show things. We talked about the three different types of charts, The Christmas Tree (or The Xmas Tree), The Box, and The Cup. The names are stupid because the only one that works like its shape is The Christmas Tree. Why does The Cup chart look like a shape that wanted to be a circle, that is not what a cup is. The Box isn't a box, it's a rough shape of a box with lines jutting out everywhere so it looks like a shape that isn't a box. So, if I were the people who did stuff with charts, I'd try to rename the charts because they don't work well, besides The Christmas Tree.
