Libs needed

Hi all,

I have the following problems with Vaadin.

I have an existing program, which can draw circles to show memberstructures.

I am looking for a library, which can rectangles draw.

Furthermore, I am looking for a library, which can circles overlap to add a number to the circle

thank-you

You could create your own Vaadin component wrapper for the GWT Graphics library. In that case, you can also take a look at ProcessingSVG that is implemented using it.

If you don't need to support browsers that do not support HTML5 Canvas (mostly IE and older versions of other browsers), it is probably easier to use the CanvasWidget add-on.

Finally, you could also draw to a suitable bitmap format or similar on the server side with some other library or Java2D, and then just display the image.

Others may have more ideas.
