In a Silverlight application I have large images which have flow charts on them.

I need to handle the clicks on specific hotspots of the image where the flow chart boxes are.

Since the flow charts will always be different, the information of where the hotspots has to be dynamic, e.g. in a list of coordinates.

I've found article like this one but don't need the detail of e.g. the outline of countries but just simple rectangle and circle areas.

I've also found articles where they talk about overlaying an HTML image map over the silverlight application, but it has to be easier than this.

What is the best way to handle clicks on specific areas of an image in silverlight?
