Hi anoopsrinivasan,
The Office suit installed from Office 356 portal on Mac is Office 2011 for Mac which has some difference from Office 365 ProPlus or Office 2013.
Based on my tests and searches, there is no PowerView in Excel 2011 for Mac. However, we can insert PivotTables going to Data> pivot table. Sorry for any inconvenience.
Based on this situation, could you submit feedback to our engineering team via the following link? http://g.microsoftonline.com/0BX11EN/135. The new feature releases often originate from customers' feedback. We appreciate your understanding.
Best Regards,
Iris He
