Creating Visualization Gadgets

This document describes how to create a visualization gadget. Gadgets are small, self-contained applications that can be added to certain web pages (for example, iGoogle and Google Spreadsheets) or on the desktop, using Google Desktop. Gadgets are simpler for users to embed: they don't require the user to modify any code on the host page, and can typically be added with a menu click on the host page. They can also store user preference values persistently.
