Erno did a great presentation about silverlight 2.0 last night. He showed what features are available and did a demo of a simple products picker that he skinned live during the presentation.
One of the things that people asked about were charts in silverlight. I can perfectly imagine why you would want charts made with silverlight in your web applications. Silverlight is just that much better at doing charts and it doesn’t have to take much time to make a chart in silverlight.
The guys at http://visifire.com/ made an open source product for creating silverlight charts complete with a chart designer to generate the charts online. That should help get developers started very quickly.
