[Feature] Ability to exponentially scale the size of a node in Sankey charts

[KurtGokhan]

What problem does this feature solve?

Imagine a Sankey chart like this where the value of a node is disproportionally bigger than other nodes.

The chart looks accurate but it is not useful to see the relative differences between nodes. A more useful way to show this data would be to scale the data exponentially and render it like that:

What does the proposed API look like?

The Sankey series should support exponent: number option and its default value should be 1. It should exponentiate all values with this number before calculating the layout.

Your solution is great and it will take one line of data pre-processing code - Demo.
So I doubt developers will be interested to add an extra parameter.

[KurtGokhan]

Yes but then you have to handle tooltips and possibly other interactions in a custom way. I am asking for a way to change the layout of the chart, without changing the semantics.

[helgasoft]

True about custom tooltip - and that's all I see as necessary customization - Demo
