Google has released Chart tools and APIs that will enable anyone to add live & interactive charts to any web page for free of-course. Google chart tools is an attempt from Google to consolidate all of Google’s charting tools and put it in one location.However, there are no new code or new APIs its actually a consolidation of already available Google Chart API and the Google Visualization API.

What is new for developers that will be much more comfortable and interesting to work with are documentation and new feature such as -

• Revised documentation and a new page that lists all parameters on one page and a new page for each new chart type.
• Added a new chart playground for developers that lets you modify a chart URL and view changes as you type.
• POST requests are now supported, enabling chart URLs up to 16K characters.

There were many players that was offering tools & APIs (paid as well) for charts & data visuals however they necessary requirements restrict the use of same such as (Adobe flash, silverlight etc.) however Google Charts are free from such things run from client side using javascript.

The Google has finally released the Charts & visuals API in an organized and well-documented that could surely be a sweep stake in market where still many companies are offering paid version of their products having similar features.
