Gantt Chart in Mathematica using a CSV (column -ID, StartDate and Duration)

Want to create a Gantt chart in mathematica extracting data from a CSV - which has columns ID, StartDate and Activity Duration)

What have you tried?

It isn’t built-in but others have made them. For example, http://demonstrations.wolfram.com/GanttChartsAndNetworkDiagrams/

yes the example demonstrates how to create a Gantt Chart from six defined tasks, with colour coding for each tasks and blanks. How to create that from a CSV with n tasks.

Could you try to adopt the code and try to develop your own version? If you encounter any specific difficulties with code you could ask and folks here would help. You perhaps may also find it useful to look at (fro visualizations):

NumberLinePlot[
 Table[RandomInteger[10] <= x < RandomInteger[20], {k, 0, 15}], x, 
 PlotStyle -> Directive[Thickness[.03], Opacity[.5]], 
 AspectRatio -> 1/3, PlotTheme -> "Marketing", GridLines -> Automatic]
