Bloomberg Business selected its favorite graphics from 2015. My favorites are still the bubble charts, if only because they are easy for students to create. Microsoft explains how to create bubble charts in Excel here. 

As is typical, this example shows different colors as variables and different sizes for, in this case, how many millions Swiss banks paid in penalties. (If you're wondering, BSI SA paid the most: $211 million.) 

The New York Times also published its list of best graphics from 2015, including this interactive visual showing the impact of the recession on 255 industries. 

Discussion Starters: 

• Create a bubble chart with Microsoft's instructions. You'll also find YouTube videos to help. How does it turn out? For what type of information or presentation would you choose this chart option? 
• Look at the detail behind the recession visual: so much information in one graphic! Do you find it useful, overwhelming, or something in between? What's the best way to navigate a visual like this?
