Built a Marketing Analytics Dashboard in Power BI Using PostgreSQL as the Data Source

I recently built a marketing analytics dashboard in Power BI using PostgreSQL as the data source. The dashboard tracks Customer Acquisition Cost (CAC) across multiple countries, making it easy to monitor trends, compare performance, and identify spikes in acquisition costs. Features include: CAC trend analysis by country KPI cards with MoM and YoY comparisons Aggregated CAC overview Interactive heatmap for quick insights The goal was to automate reporting and provide stakeholders with a clear view of marketing performance without relying on manual Excel reports. I'd love to hear your feedback
