Alternative to Many Eyes Bubble Chart

Question

I am looking for a suitable package (free or otherwise) to duplicate the functionality (mainly in visual department) of IBM's Many Eyes Visualizations Bubble Chart in our app. Below attached a screenshot of what I am talking about. Ideally it does the following:

1. Renders with ether flash or javascript.
2. Ability to generate graphs at least once a day.
3. Ability to be interactive, i.e. clicking a bubble would be able to do a callback to our javascript
4. Looks very similar to the Bubble Chart from Many Eyes (attached below).

Any ideas if such a solution exists?

We use AnyChart a lot at work for data visualisation :

What they say on their site: "AnyChart is a flexible Flash based solution that allows you to create interactive and great looking flash charts. It is a cross-browser and cross-platform charting solution intended for everybody who deals with creation of dashboard, reporting, analytics, statistical, financial or any other data visualization solutions."

From our research, these guys seem to offer some of the most customisable charts we've found that let users display the data in the many formats we need and expose a variety of events, accessible via Javascript, such as click and hover on individual items.
