Thoughts from the BI Elite team:
The thing I like the most about Roman's report is its ease of understanding. The first page has some high-level metrics along with a trend of the dynamically selected metrics. I absolutely love that as you change your selection, the selected metric definition is explained as well, ensuring that the reader understands what they're looking at.
The report looks great with a nice contrast. The report page tooltip when hovering over the line chart on the first page is impressive as well! On the second tab, the "Mood" slicer was a hilarious and creative use of emojis. The final piece of this report that truly makes it a winner is the "Song details" tab. If you haven't already, drill all the way down to a single song. This page is laid out wonderfully to provide some details in an appealing way, and you can also click the big button in the middle to play the song directly on Spotify! That's an amazing touch that tied this report together.
Truly amazing work, Roman!
