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
---
sankey-beta

"Year","Q2",10

"Q2","April",6
"Q2","May",2
"Q2","June",2
"Q3","July",2
"Q3","August",6
"Q3","September",2
"Q4","October",6
"Q4","November",2
"Q4","December",2

showValues: true

config:
  sankey:
    showValues: true

sankey-beta
