sankey with showValues enabled results in unnecessary crossing of lines

[conan-chiles]

Description

Hi,
with the sankey diagram, the option showValues set to true results in the diagram having unnecessary crossing of lines, making the diagram less readable.

Not 100% sure if this is a bug, or maybe more a feature request where another parameter is required.

examples:

showValues: false

---
config:
  sankey:
    showValues: false
---
