Gantt Library Investigation

[e-wu]

Look into seeing if other libraries would be better as DHTMLX does limit what can be done for milestones.

When looking into each, consider:

• licensing as we need to stick to MIT/GNUv2/free (give library the credit)
• accessibility (is it baked in, PR to fix, or can we extend it to support it)
• Minimum feature set
  • Parent/Child/Grandchild tasks (aka summary tasks)
  • Milestones
  • Ability to control the chart "timeline"
  • Dependencies (predecessor/successor)
  • Show progress

Nice to have

• Critical path
• Edit mode (live editing)
• Cycle detection (dependencies create a cycle right back to parent)

Frappe Gantt

• Tried this, no parent/child tasks, so doesn't meet our needs.

React Google Charts

• Not sure if google gets a copy of the data as is it local render or server api render?
