Sankey Diagrams for funnel reports

[mathix420]

Describe the feature or enhancement

Actual funnel report doesn't really allow comparison between different user journeys.

For example my use case is the following:

• Users can create an account and then either follow a quick demo of the platform or skip the demo. I want to compare which of these user flow is more likely to finally buy a subscription to my platform.
• Right now I have to create two different reports and compare them, by opening two chrome windows side by side.
• And for this example I have only two possible events, but I have some flows where users can take 8 path to achieve same result, I want to be able to compare those path and identify quickly which one is the most performing one.
• I can also have multiple source events converging to the same final event. For example affiliate-signup paywall-signup home-signup end-cta-signup will all ultimately converge to pay-modale or pay-page and then abort-payment or pay-btn

This one is not a sankey diagram, but could also be helpful (https://github.com/greghub/funnel-graph-js):

Here we can clearly and quickly see that direct traffic is the best performing one.

We have a separate Sankey Report in our plan that will be able compare different user journeys. Will label enhancement so it doesn't get stale.
