This means that your UI libs needs some way of displaying html and executing javascript to be compatible with Plotly.NET. That is true for most UI libs though, here for example is a POC for Blazor.

The link to POC Blazor in the FAQ leads elsewhere. At least it is not clear how https://github.com/plotly/Plotly.NET/blob/dev is a POC.
