Is it possible to alter the path colour of Tree Vega chart depending on a data field where the condition is, flag == 1 imply path should be in red else black in colour, I used the following code for the node and it works good, but I wanted to implement the same for pathways as well, Please advise.
"stroke": [
{"test": "datum._source.flag==1", "value": "#de040c"},
{"value": "#10a5e6"}
]
