Gantt Chart using Yii ?

So I want to create a Gantt Chart with Yii, anyone can point me in the right direction ? My gantt table has the following fields at the moment :

id - int

start_date - date -> defines the start date of a gantt chart

end_date - date -> defines the end date of the chart

duration - int -> stores the number of days

task - varchar ->stores the tasks of the chart

project_id - int -> stores the projectId to which the chart is associated, FK

Thx in advance if anyone can give me some tips :)

And what do you using now for it?
