The above example shows you how to create `BubbleChart` using built-in Google Charts. In this example, for purpose of chart demonstration only, we do use mock-up data from array. As you can see, the KoolReport's widget in general support dataSource could be DataStore, Process, DataSource or even simple array.

For example:

    ...
    "options" => array(
                ...
                "bubble" => array(
                    "textStyle" => array(
                        "fontSize" => 11,
                        "fontName" => 'Times-Roman',
                        "color" => 'green',
                        "bold" => true,
                        "italic" => true
                    )
                )
            )
