Teasing Dashboard reports. Use dummy data or empty reports?

I’m currently designing a dashboard that relies on having a connection to Google Analytics. For the users that aren’t connected to GA, what would be best to show for them? We want to have a strong CTA to connect to google analytics while teasing the reports that would become available once they’re connected.

Option 1. Show empty reports, with the “connect to GA” call to action. Tables and graphs would be present but with no data in them

Option 2. Show dummy data with some sort of treatment to indicate that this is not real data and again with the “connect to GA” call to action

Option 3. something else
