Dreamforce 2008 brought many exciting new features from salesforce.com, both on the CRM/front-end side and the Force.com platform/back-end side. One of the favorites was the announcement that salesforce.com had released a Google Visualization code share project. Google has invited developers to participate in Developer Preview Releases for the Visualization API.
It looks like a pretty cool way to work on RESTful integrations while making some pretty pictures for your users.
For those unfamiliar with the Salesforce/Google Visualization toolkit, developer.force.com has a great introduction.
