Each mark is a design, placed by its factors and runs. The lines are the fewest
runs each model needs: a design below a line cannot estimate that model. Drag a box to filter; click a mark
to open its design. The published designs by the year their source appeared, in the
colours of their families; a diamond marks the year a family was first published. Drag across the years, or
choose a bar, to keep those years.
