Introduced ChartClickEventArgs to encapsulate click event details. Added OnClick EventCallback to chart components (BarChart, LineChart, PieChart, etc.). Updated JS to wire up Chart.js onClick handler and invoke Blazor method with event data. Added demo for bar chart click event. Ensured proper disposal of DotNetObjectReference.

Added new "Click event" demo sections to the documentation pages for Doughnut, Line, Pie, Polar Area, Radar, and Scatter charts. Each demo shows how to handle chart element click events, display selected item details, and update the UI accordingly. New Razor demo components were created for each chart type, and documentation was updated to include and link to these interactive examples. This enhances guidance for handling user interactions in ChartJS-based Blazor charts.
Updated documentation for all chart components to include "Events" and "ChartClickEventArgs Properties" sections. Enhanced BlazorBootstrapChart property metadata with [AddedVersion], [DefaultValue], and [Description] attributes for Height, HeightUnit, Width, and WidthUnit. Improved remarks to clarify default values.
