Hi everyone,
few nodes and associated labels are getting overlapped when I am creating a Holoviews Chord plot using a custom json dataset.
I have tried customize the inbuilt option
padding, responsive, height but with no luck. Someone please help me resolving this.
My code for building this Chord:
edge_data = [{"from": "Maulana Saheb", "to": "Lady Anna", "value": 1}, {"from": "Maulana Saheb", "to": "Mahadev", "value": 1}, {"from": "Maulana Saheb", "to": "Netaji", "value": 1}, {"from": "Maulana
