One shared scale, so flat really means small, and the spike in New Zealand is unmissable even from the bottom of the tail. Drag the card's bottom-right corner: the grid recolumns 4 → 3 → 2 → 1 from the container width alone.
minPanelWidth: 240 is the whole configuration, and the
trellis's single ResizeObserver recolumns the SAME panel instances (no
re-creation, no re-mounting) as its container changes. The bottom row's
x labels and the first column's y labels follow the new edges
automatically; label space is reserved in every panel, so the plots stay
pixel-aligned through every layout. Above 64 panels the grid would also
virtualize automatically. Trellis is a premium feature; without a license
it renders with a trial watermark.
