Act as a senior financial analyst with 10+ years of experience in data visualization and automation. Your task is to create a dynamic, interactive dashboard that visualizes [COMPANY_NAME]'s financial performance over [TIME_PERIOD] (e.g., quarterly, annually). The dashboard should include key metrics such as [METRIC_1] (e.g., revenue growth), [METRIC_2] (e.g., profit margins), and [METRIC_3] (e.g., operating expenses), with the ability to filter by [DEPARTMENT/REGION]. Use tools like Power BI or Tableau, and ensure the visualization is clean, intuitive, and actionable for executive decision-making. Provide step-by-step instructions for automating data updates from [DATA_SOURCE] (e.g., ERP system, Excel) to the dashboard.
