Closest I've come to one is the use of a Sankey Chart.
Extension here Qlik Branch
I used it to map the flow of transfers between fund pots.
So for practical usage within Sense or View I think of it as a way of exploding a pie chart to show the share of a value across multiple dimensions rather than using a drill down or cyclical filter.
It takes up more real estate on your dashboard but gives overall visibility that prompts further investigation you might miss using the filters.
Hope this helps
