Modules

Generates a Gantt Chart. Bars are drawn for each task covering the start and end time for each task. In addition, tasks can be grouped into categories which have a different coloured background - this is useful for showing projects that are in major phases. The time interval columns must be of a date time type (either NaiveDateTime or DateTime) Labels can optionally be drawn for each task (use show_task_labels/2) and a description for each task, including the time interval is generated and added as a '<title>' element attached to the bar. Most browsers provide a tooltip functionality to display the title when the mouse hovers over the containing element. By default, the first four columns of the supplied dataset are used for the category, task, start time and end time.
