Here is a [example] (http://static.mentful.com/d3ganttchart/example.html) of loading external data, in JSON format, into the Gantt Chart, you need to watch out for [cross-domain restrictions] (http://en.wikipedia.org/wiki/Same-origin_policy).
Create a array of task names, they will be display on they y-axis in the order given to the array.
var taskNames = [ "D Job", "P Job", "E Job", "A Job", "N Job" ];
Create a simple Gantt-Chart
var gantt = d3.gantt().taskTypes(taskNames).taskStatus(taskStatus);
gantt(tasks);
Relies on the fantastic D3 visualization library to do lots of the heavy lifting for stacking and rendering to SVG.
