Google visualization team released a new type of annotation visualization called AnnotationChart that currently does not have a GWT wrapper. It is meant to replace old Annotation Timeline which is plagued by issues such as these and make a transition from flash to SVG/VML.
I was wondering if anyone has used Annotation chart in GWT before and if yes, what's the easiest way to integrate it into java code?
If not, does anyone who has written wrappers for js libraries for gwt know where should I start with this?
If anyone else stumbles on this and needs an answer, here you can find the wrapper that I wrote for this purpose. It can be used in the same way as any other google chart classes.
