Simulated home power draw by device category, over a single day — illustrative, not measured.
Switching to "Overlapping Lines" draws the exact same three series as plain lines
instead: notice how the individual HVAC/Lighting/Electronics shapes are actually easier to compare
that way, but the *combined* household draw at any hour — the thing stackedArea
shows directly as the height of the whole stack — disappears entirely once the lines are just
laid on top of each other.
