Power BI Funnel Chart
The Funnel Chart allows you to see the percentage difference between values. Normally, the highest value is at the top and the lowest is at the bottom, which gives the look of a funnel.
With this type of design, it makes sense that the Funnel Chart is very effective when visualising a linear process with at least three or four stages.
Waterfall Chart is very helpful in understanding the changes that occur from an initial value. It displays a running total in relation to values being added or subtracted. By populating a field in the Breakdown option of the visual, you can see if it has had a positive or negative impact from value to value.
