Good Power BI Sample report with best practice on Data Model and Visuals

Hi I am looking for a good Power BI Sample report with simple star schema model behind it. I have seen the official MS one and the data model in the report uses all bi-directional relationship which something they also recommend not to use it in the modelling layer. The purpose is to show case to business about how a simiple power bi report with star schema will look like.

Thanks in advance for your input.
