Interactivity

The dashboard includes a filter for Region. When a user selects a region, all components update to show data only for that region. For example, selecting "North" updates the KPI cards, bar chart, line chart, and details table to reflect only sales from the North region.

Self Check

If you add a filter for Region = East, which components update?

• Both KPI cards show totals only for East region.
• Sales by Region bar chart highlights East region data.
• Sales Trend Over Time line chart shows sales trend only for East.
• Sales Details Table lists only sales records from East region.

Key Result

A Power BI dashboard showing total sales, units sold, sales by region, sales trend over time, and detailed sales data with region filtering.
