Rounded corners on hover text

Hi All,
Is there a css tweak that allows me to create hover text with “rounded corners”. Any idea how to achieve that?
Cheers

Hello, I don’t think this is possible at the moment. There have been discussions about the possibility to add generic css to the hoverlabel parameter of traces, see https://github.com/plotly/plotly.js/issues/2342. I’ve added a link to your question in this issue for the record.
