This is a demo tutorial. While there is no step-by-step commentary available (yet), the live demo below is fully functional. Feel free to open it for full source code.
This demo shows a Gantt chart with externally-loaded JSON data.
It uses built-in net.load utility to load and parse data, as well as a data processor to parse dates and color codes in data.
