/*You need to include the following JS file, if you intend to embed the chart using JavaScript.
Embedding using JavaScripts avoids the "Click to Activate..." issue in Internet Explorer
When you make your own charts, make sure that the path to this JS file is correct. Else, you would get JavaScript errors.

In this example, we show how to connect FusionCharts to a database.
For the sake of ease, we've used MySQL Database.
It just contains two tables, which are linked to each other.
