The perspective effect in Piwik Pro is a visual representation designed to compare two months of data dynamically from the demo account of Piwik Pro. It creates an illusion of depth and dimension, making the data comparison more engaging and visually appealing.

To create the perspective effect in Piwik Pro, the following components have been implemented:

• A simple data set with consents to remarketing by device type
• Two bar charts
• Two dropdown controls and parameters to select the compared months
• Images for the device type icons, bricks, and the background and frontend charts
• Calculated fields to filter the metrics according to the chart and the selected value in the controls

To access the shared report with the perspective effect in Looker Studio, you can follow the prompt in the text that says 'Go to the shared report'. This implies that there is a link or a shared access point provided to view the report in Looker Studio.
