Thank you for your challenges I have been reading about each challenge but couldn’t join. But recently I picked it and tried to submit it.
Here in this Report I have used bookmarks for slicer at top left and below it another bookmark to clear any filter.
Have removed the data labels for more space( i noticed that I missed 1 to remove ) and added image at bottom. I have used simple DAX measures whereas kept my data model as star schema. In the Detail View I used Decomposition tree to show the distribution for each level.
For line chart may be I should have used when I am showing against date and should have added tooltips for getting more information.
Overall I learned a lot from the forum with very beautiful report ( may be I don’t have that skill of UI) .
