While watching this video demo, on this Vaadin blog post, about the new Vaadin plugin 1.1.x for NetBeans 7 IDE, I noticed this very simple example being done with Vaadin Charts 1.1.x. Just 3 lines of code.
Vaadin Charts can be a bit overwhelming to approach because of its huge power and flexibility. So I was glad to see, and try, this little "Hello World" example.
NOTE: Vaadin Charts is a commercial product, requiring a paid license. A 30-day free trial is available.
Chart chart = new Chart();
chart.getConfiguration().addSeries( new ListSeries( 1, 2, 3 ) );
layout.addComponent( chart );
You can simply add that code to the default app created by the Vaadin Plugin, and run.
See this YouTube video for another demo of Vaadin Charts, from their webinar.
