Hey,

if you inspect the webpage you will discover something like this

<iframe allowfullscreen="true" frameborder="0" height="1250" 

src="https://app.powerbi.com/view?r=eyJ...OjN9" width="100%"></iframe>

So, what you see is not a visual with a vertical scroll bar, but instead it's an complete report rendered in an iframe.

Basically, design a report publish this report to Power BI Service, make sure that this report does not contain any confidential data 🙂

Use the Publish to Web

https://docs.microsoft.com/en-us/power-bi/service-publish-to-web

to create something that can be embedded into your website

Hopefully this is the answer you were looking for.

Regards,
Tom
