A basic implementation of a Gantt Chart using D3.js. Here is an example [Example 1] (http://bl.ocks.org/dk8996/5534835) and another one [Example 2] (http://bl.ocks.org/dk8996/5449641).

Here is an [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 an array of all your data.

var tasks = [

{
    "startDate": new Date("Sun Dec 09 01:36:45 EST 2012"),
    "endDate": new Date("Sun Dec 09 02:36:45 EST 2012"),
    "taskName": "E Job",
    "status": "FAILED"
},

{
    "startDate": new Date("Sun Dec 09 04:56:32 EST 2012"),
    "endDate": new Date("Sun Dec 09 06:35:47 EST 2012"),
    "taskName": "A Job",
    "status": "RUNNING"
}];

Create a map between task status and css class, this is optional.

var taskStatus = {
    "SUCCEEDED": "bar",
    "FAILED": "bar-failed",
    "RUNNING": "bar-running",
    "KILLED": "bar-killed"
};

  .bar {
      fill: #33b5e5;
  }
  
  .bar-failed {
    fill: #CC0000;
  }

  .bar-running {
      fill: #669900;
  }
  
  .bar-succeeded {
    fill: #33b5e5;
  }

  .bar-killed {
      fill: #ffbb33;
  }

Create an 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.
