Looker Marketplace Sankey Broken With Latest Update

[sh_]

Hi there,

I wrote a data model to work within the limitations of the sankey visualisation available on the marketplace. Specifically, the visualisation did not allow for loops and required each unique journey to be tabulated. Unlike python library sankeys which only require a list of event combinations and counts of combination occurrences. 

With a recent Looker update my model is no longer visualised sufficiently. 

Outstanding issues with sankey following update:

• hard 50 row limit

• loops (now introduced) fall outside of viz borders

• no option to show values

• viz is blank for many of the different journey iterations

Complex journeys sometimes have more than 50 different journey types (can change filters, but I don't know if this limit existed prior to the update?).

Complex journeys have loops (same event repeated in later steps). No way to edit viz.

Want numbers on viz. No option to add.

Viz blank. Error in rendering of viz for some iterations. Unclear on what causes this and how to fix it.

Would appreciate suggestions to work around the above issues or any updates on potential fixes.
