I need a fully-interactive marketing performance dashboard built in Power BI that lets me slice and explore data by channel, campaign, lead source, and region. The core data set includes social media, email campaigns, and paid search; from it I want to surface four headline KPIs—Total Revenue, Total Budget, Conversion Count, and ROI %—and be able to drill down quickly with dynamic filters, date-range controls, and campaign-level selectors. The visual layer should rely on clear, insightful charts and graphs: • side-by-side budget-versus-revenue comparisons for each channel • trend lines that react instantly when the date slider is adjusted • conversion funnels or stacked visuals that reveal strengths and gaps across regions Behind the visuals, please set up calculated measures so ROI and other metrics recalc accurately as filters change. I’ll provide the raw tables; you handle data modeling, relationships, DAX, and any needed data-cleaning steps to keep refreshes smooth. Deliverable: a .pbix file ready to publish to Power BI Service, clearly labeled and organized, plus a short walkthrough (video or live) so I can extend the report later.
