title: GANTT Chart with Shapes
body: <p>I'm trying to create something like a GANTT Chart where I would have start dates and end dates designated by a shape like a diamond and then the period of time in between connecting the start and end date shown as a line connecting the shapes.  Does anyone have any tips on how to do that in tableau?</p>
  
  <p>For data I have an identifier column, an event column, a date column, a start date column, and  an end date column.</p>
