How to display in sharepoint?

Embeding PowerBI visuals is not yet supported..

The link you post is not from PowerBI service but from excel files with powerview sheets stored in onedrive business..(office 365, I think E3 and up )

The limit is 10MB per file as in sharepoint online to render the file..

Also in a web part in a sharepoint oline site you can show a powerview report from excel file..Also needs to be stored in sharepoint online.

With some small changes you can make it work:
