In my short recent burst of creating new "How To..." YouTube videos, my most recent two are closely related. Excel has become a lot better at Data Visualization and now has options to draw sunburst diagrams and tree maps in the Office 365 version. These type of charts are great for displaying hierarchical data. They are really easy to create, and also easily modified. Enjoy!
