This chart is a work of art. I hope multiple people got paid well to make it and I hope they get hit by a bus pic.twitter.com/XS6aWwwj7P

Charts and graphs can be wonderful for breaking down information and showing trends over time, but only if they are constructed in a way that people can understand. On TV, the viewer only has a short period of time to grab that information, but when you take a screenshot, you see that there are many things wrong with this graph. Mefite Stark takes a stab at listing them.
1. The y-axis doesn’t start at zero
2. The y-axis isn’t labelled correctly (it should be % of Adults who report that they think violent crime is a problem)
3. The gaps between the data points on the x-axis are not representative of the gaps between the dates
4. The margin of error is not highlighted on the chart’s data points
5. Straight lines between the data points imply a steady trend which may or may not be the case
6. In my opinion the most amazing weirdness is that the x-axis dates go from right to left!
Someone else mentioned that the x-axis is labeled in alphabetical order. Andy Baio took the information and made a much better chart.
Listen beautiful relax classics on our Youtube channel.
Wait so it isn’t even for actual violent crime? Just adults who THINK there’s a violent crime problem?????

This is far from unique, though, as many media outlets rely on their graphics departments (or maybe an intern) to make charts instead of data scientists. You can go down the rabbit hole and see plenty of confusing or misleading information in charts here, here, and here. In fact, there are so many ways to make a bad chart that several sites are dedicated to explaining and shaming them. See more terrible charts archived at Bad Visualizations, WTF Visualizations, and the subreddit Data Is Ugly. -via Metafilter
