If you head to the link above you will probably come to the same conclusion I and a lot of other people thought, WHY??!! Earlier in the semester we discussed data visualization and its uses, but I'm sure the people at CNN needed that lecture just as much as we did. As I watched some of the CNN coverage early in the day I noticed that they had tried their hardest to visualize data in many different ways, the one which they showcased the most was a touch screen. The main problem I have of their presentation of this information is that the intention was to watch someone else interact with the information they had. Because of this I ( and probably most viewers) could not retain any of the information that was on the touch screen, as the correspondent who used it would navigate the information at his pace (which was super fast) and not at a pace I would have liked. Their experiment of failures culminated with the "Hologram," which was completely absurd. We should all take notes on how not to visualize data.
