Swiff Chart offers you a chart system very similar to the one offered by Microsoft Office, although it offers some power ups that make them more attractive. The main feature is that one that makes possible to generate animated charts where bars appear step by step.
You can create different kind of charts and the animations are different depending on the kind of chart you create. Besides, you can apply different visual styles and effects.
Finally, you can save the results as a Flash Movie or as a picture and you can choose if you will enter data manually or import from Excel.
