What is the Google Visualization API?
The Google Visualization API lets you access multiple sources of structured data
that you can display, choosing from a large selection of visualizations. Google
Visualization API enables you to expose your own data, stored on any data-store
that is connected to the web, as a Visualization compliant datasource. Thus you
can create reports and dashboards as well as analyze and display your data through
the wealth of available visualization applications. The Google Visualization API
also provides a platform that can be used to create, share and reuse visualizations
written by the developer community at large.

-
Embed visualizations directly into your website:
Display attractive data on your website by choosing from a vast array of
visualizations created by the developer community.
-
Write, share, and reuse:
Write visualizations and also wrap them as Gadgets with the simple
Gadget Extensions of the API.
Publish these here
or in the
Gadget Directory.
Become an active participant in the developer community; reuse and share
visualizations with others.
- Create dashboards and reports over your own data: Expose your
data stores as Google Visualization-compliant data sources. Create dashboards and
publish your insights (within your domain or publicly) anywhere on the web.
-
Create extensions to Google products:
Write visualization applications for Google products such as
Google Docs.
Syndicate your application with a growing list of products that support Gadgets.
-
Use many data sources, one API:
Visualizations created using the API are able to access any
compliant server-side data source, or access data directly from the client using
JavaScript, with no required code changes to your application.
