 * Fix layout of demo-flow.json so nodes are nicely grouped and don't overlap.
 *
 * Layout structure (on demo_tab_wwtp):
 *
 * Row 1 (y=40-300):   PS West section (comment, mode injects, pumps, MGC, PS, q_in sim)
 * Row 2 (y=340-500):  PS North section
 * Row 3 (y=520-680):  PS South section
 * Row 4 (y=720-920):  Biological Treatment (measurements, reactor, settler, monster)
 * Row 5 (y=960-1120): Pressure Measurements section
 * Row 6 (y=1140-1440): Effluent measurements
 * Row 7 (y=1460+):     Telemetry & Dashboard API
 *
 * Column layout:
 * x=140:   Inject nodes (left)
 * x=370:   Function nodes
 * x=580:   Intermediate nodes (measurements feeding other nodes)
 * x=700:   Main equipment nodes (PS, pumps, measurement nodes)
 * x=935:   Link out nodes
 * x=1050+: Right side (reactor, settler, telemetry)
