There should be a filter bar allowing the user to:

• Select time period (e.g., this month, last 3 months, custom range in months).
• Filter by Customer — choose one specific customer or view aggregated data (“All Customers” / “General”).

Expected behavior:

• When the user changes the time period or customer selection, the graph and values update accordingly.
• The dashboard remains generalized — it provides an overview rather than deep per-service details.
