Graphs and Data

I thought the video we saw in class made graphs a lot more interesting to watch. Those graphs included a lot of information, and it was easy to understand. Another good thing was that you could see the changes of time of the data that was collected. Someone who isn't good at reading graphs well could easily understand an animated graph.
