Using the Excel Sunburst Chart for Visualizations
Though not a new concept, Office 365 (Excel 2016) has a Sunburst Chart type (a.k.a. Multi-level Pie or Donut Chart) that is very handy for presenting hierarchies. Here are some ideas to consider: A series of project portfolios: A phone "wheel" like a phone tree (recently used this idea myself): There is more sophisticated color formatting available in a variety of JavaScript libraries such as FusionCharts and HighCharts , but having the chart type in Excel makes it very approachable for those wanting an ad hoc visualization that doesn't require any programming.
