 - Fully functional area chart component using ApexCharts
 - Displays time-series data with gradient fills
 - Responsive with ResizeObserver (debounced to prevent flicker)
-- Demo shows CPU and memory usage metrics
 - Fixed: Chart now properly respects container boundaries on initial render
 - Overflow prevention with proper CSS containment
+- Enhanced demo features:
+  - Multiple dataset examples (System Usage, Network Traffic, Sales Analytics)
+  - Real-time data simulation with automatic updates
+  - Dynamic dataset switching
+  - Customizable Y-axis formatters (percentages, currency, units)
+  - Data randomization for testing
+  - Manual data point addition
+- Properties:
+  - `label`: Chart title
+  - `series`: ApexAxisChartSeries data
+  - `yAxisFormatter`: Custom Y-axis label formatter function
+- Methods:
+  - `updateSeries()`: Update chart data
+  - `appendData()`: Add new data points to existing series
