Thanks a lot for the gantt charts in plantuml.
It would be great if there were a way to break a gantt chart over multiple lines. This would be useful for long gantt charts that become unreadably small on one line. See https://forum.plantuml.net/12043/
for a related request.
As a work around: Is there a way to define two gantt charts in one figure. I have not found a way, see also https://forum.plantuml.net/13673
