Include a chart as shown in your webpage using Google API

The Google Chart API lets you dynamically generate charts. It returns a PNG-format image in response to a URL.

Several types of image can be generated: line, bar, and pie charts for example. For each image type you can specify attributes such as size, colors, and labels.

You can include a Chart API image in a webpage by embedding a URL within an<img> tag. When the webpage is displayed in a browser the Chart API renders the image within the page.
