Improving a dashboard

Here's another dashboard, which you may remember from the first chapter. It's the dashboard of data collected by vibration sensors on the Brooklyn Bridge to measure the amount of traffic. Since the first chapter, you've learned more about visualization, so take a closer look at this dashboard and see if you can come up with some suggestions to improve it.

Remember, some of the plots in the dashboard are interactive and may change as you interact with them. You can always reset any plot to its original state by double-clicking it.

Which suggestion would you not give?
