If you want to make one of these yourself in your presentation these are the instructions:
- Download the example pptx file here
- Copy the chart and paste it into your slides-enabled presentation
- Select each shape containing the numbers or charts, and select Shape settings
- Select a single column containing 3 responses, for each statement.
Slides! will do the rest for you and your shapes will stay in touch with your data no matter how much it changes.
