Devin Knight shows off the horizontal funnel Power BI custom visual:
In this module you will learn how to use the Horizontal Funnel Power BI Custom Visual. The Horizontal Funnel functions somewhat similar to the traditional funnel but it allows you to display a secondary measure and has a few more customizations than you would normally get. You’ll find that the Horizontal Funnel is great for displaying a flow of data.
One of the better non-sales uses of funnels I’ve seen is tracking completion rates on multi-page forms or multi-step processes. If you see a huge drop-off at one step in the process, it might indicate a bug in the form or some incongruity with the end user’s expectation.
