Find and post a data display, such as a pie chart or a scatterplot. Don't use specific examples from the notes--find your own--but it can be about any data. Find something wrong with the data display, such as it seems decieiving or it's hard to read. Be sure to include a link to the original display.

For responses, suggest a correction that would solve the original poster's problem. Be sure to be sensitive to any downsides to your solution (for example, "make it bigger" might result in too large of a file size). The best corrections suggest a good alternative chart entirely. It's also fine to say that you don't know how to improve the display as long as you make it clear why it's hard to come up with a solution.
