Is there a way to gracefully handle missing parent node in kibana/vega tree visualization? For example, if the below json represents data, since X is non existent parent is it possible to ignore that link?
This is more of a Vega question than a Kibana question, but we can try to answer. I think this is technically possible, but I don't see why you would want to: the format you've shown is what Vega expects for their tree layout examples.
Yes, the format here works, but I believe the transform to convert this to tree(stratify) throws error missing: X (as X is not in the ids). Let me go through your suggestions to see if they help.
