Old version with Blazor.Diagrams 2.0 instead of 3.0.2 - does not work with latest

[joslat]

Even being a cool example, it does not work as an example due to the breaking changes on the later version.
Is there a "upgrade tutorial"? anyhow it would be great to have this updated as I tried to follow the steps re-implementing this and everything seems to break.

Thanks for putting this together though - great library! :)
