- Integrated the `build_vitals_history_and_analytics` function into the recovery dashboard to provide historical insights on vital signs. - Updated the `get_recovery_dashboard_viz_bundle` function to include a new chart for vitals history, enhancing the data visualization capabilities. - Enhanced the `RecoveryDashboardOverview` component to render vitals history, including improved messaging for insufficient data and visual representation of trends.
