The Power BI challenge for Week 21 on Workout Wednesday involves creating a budget analysis report using slicers to filter visuals based on measure amounts. Participants need to load data from Data.World, create slicers for expense amount, budget amount, and budget percent used, and display the filtered results in a table showing project details for the year 2024. An advanced task includes adding an SVG for a horizontal lipstick chart comparing expense vs. budget. This exercise aims to enhance skills in data manipulation and visualization in Power BI.
