What are the differences between Gadget Visualizations and Javascript Visualizations?
Here are the major differences: • Gadgets run in separate iframes and are therefore safer to place on any webpage, even if they are developed by 3rd parties. They are also easily publishable and shareable on Gadget containers, such as iGoogle, etc. However, they require more server calls and it is very difficult to create inter-gadget communication. • Javascript code runs directly on the webpage and is therefore less “safe”. However, the advantage of Javascript is lower latency and the ability to access the Gviz Event Model. With events, you can easily create dashboards in which one visualization is tied to others on the page. This example shows how you can listen for events so that clicking one visualization can affect the focus of another.
