Data preparation is the key to unlocking the full capability of the native visual and this customised visual. The guide included in the zip file focuses on getting your data model right before touching any visual settings.

The dependency lines feature included is basic and configured for monthly timeline view only - it may not work correctly with other timeline types such as weekly or quarterly. It demonstrates the concept and can be extended to suit your requirements. This resource is built on Microsoft's open-source Power BI Gantt visual, available on GitHub.
