How to integrate the Fusioncharts library with Drupal 7?
There's a couple of problems in your code:


include($path.'/Code/PHP/Includes/FusionCharts.php'); you have to use ./ to include files.
include($path.'/Code/FusionCharts/FusionCharts.js'); you should use drupal_add_js() to include javascript in your code.
FusionCharts documentation seems a little old as Column3D.swf is now FCF_Column3D.swf


Here is a working example, I haven't used the librarie module but you should be able to adapt it easily. I put this code in a node with PHP filter activated.

&lt;?php
$file = './sites/all/libraries/FusionChartsFree/Code/PHP/Includes/FusionCharts.php';
if (is_file($file)) {
  require_once $file;
}
drupal_add_js('sites/all/libraries/FusionChartsFree/Code/FusionCharts/FusionCharts.js');

//Create the chart - Column 3D Chart with data from Data/Data.xml
echo renderChart("/sites/all/libraries/FusionChartsFree/Code/FusionCharts/FCF_Column3D.swf", "/sites/all/libraries/FusionChartsFree/Code/PHP/BasicExample/Data/Data.xml", "", "myFirst", 600, 300, false, true);
