Interactivity

A filter for State allows users to select one or multiple states.

When a state is selected:

• The Symbol Map updates to show only cities in the selected state(s).
• The Sales Details Table filters to show only those cities.
• The Total Sales KPI recalculates the sum of sales for the selected state(s).

Self Check

If you add a filter for State = CA, which components update and what do they show?

• KPI Card: Updates to show total sales for California only (200000).
• Symbol Map: Shows only San Francisco with a circle sized for 200000 sales.
• Sales Details Table: Shows only San Francisco, CA with sales 200000.

Key Result

A dashboard showing total sales and sales by city on a symbol map with interactive state filtering.
