If you're just getting started with Wt, these tutorials are good place to start.
This example demonstrates the Wt charting widgets that are implemented on top of Wt's cross-browser painting API. This painting API uses built-in browser support for generating high quality graphics. Depending on the browser, inline VML, inline SVG, HTML5 canvas, or a PNG image is used to render painted contents in a WPaintedWidget.
This example also demonstrates how a Model can be shared by several Views, and pass modification events to each connected View. The table view and the chart implement a View on the same item model.
