  Produce Gantt charts using the Google Charts API
  Author: Adam Bard,
  This api is designed to allow you to easily and quickly create gantt charts using the Google Charts API. You can save them as images or just produce a URL.
  It works swell as long as you want things measured in days.
  The method of producing such a chart is heavily influenced by this post by Dave Goerlich. Thanks, Dave.
  Quick Start Example
  from googlegantt import GanttChart, GanttCategory gc = GanttChart('Test Chart', width=650, height=200, progress=(2011, 02, 27)) on_time = GanttCategory('On Time', '0c0') late = GanttCategory('Late', 'c00') upcoming = GanttCategory('Upcoming', '00c') t1 = gc.add_task('Late Task', (2011, 02, 20), (2011, 02, 25), category=late) t2 = gc.add_task('On Time Task', depends_on=t1, duration=3, category=on_time) t3 = gc.add_task('Future Task', depends_on=t2, duration=7, category=upcoming) url = gc.get_url() image = gc.get_image()
  Produces:
  Features
  - Optional Progress indicator shades the elapsed area of the chart.
  - Flexible chart width and height.
  - Specify task colors using css rules.
  - Flexibly specify dates using datetime.date objects, or tuples.
  - Produce a Google Chart url, or a png image (requires PIL).
  - Date span is automatically computed from tasks.
  Classes
  There are 3 primary classes involved in the creation of a chart.
  GanttChart
  GanttChart(title,[ **kwargs])
  Produce a Gantt Chart.
  Keyword Arguments:
  - width The width of the chart.
  - height The height of the chart.
  - progress A date representing the current time, to produce a shaded 'elapsed' region.
  Example initialization:gc = GanttChart('Test Chart', width=600, height=200, progress=(2011, 02, 27))
  Methods:
  GanttCategory
  Optional in common usage. Represents a class of Tasks with a color and a title.
  GanttCategory(title[, color])
  Produce a category object with a given color. Color is specified using a hex string, and will be converted to an 8-byte rgba hex color string expected by Google Charts from any of the following formats:
  - 3-byte, e.g. 'f00' => 'FF0000FF'
  - 4-byte, e.g. 'f00c' => 'FF0000CC'
  - 6-byte, e.g. 'ff0000' => 'FF0000FF'
  - 8-byte
  GanttTask
  Represents a single bar in the chart. Must have a specified start and end date, although these can be computed in different ways.
  GanttTask(title[, start_date=None, end_date=None[, **kwargs]])
  Keyword Arguments:
  - start_date The start date of the task
  - end_date The end date of the task
  - duration The duration, in days, of the task. May be used instead of end_date
  - depends_on A GanttTask that must be completed before this one can begin. May be used instead of start_date
  - category A GanttCategory to apply to this task.
  - color A quick way to specify color. Don't use this when you have categories declared, you will get blank legend entries.
  Either start_date or depends_on must be specified. Same with end_date and duration.
  If both start_date and depends_on are specified, depends_on is used.
  If both end_date and duration are specified, duration is used.
