The graphic above shows two graphs, each with a quadrilateral polygon pulled along four axes. The two axes are perpendicular to one another, like in a typical graph, and each direction represents a different dimension of interest: demand, mode share, congestion, and accessibility. Each corner of the polygon is on an axis, and the closer the corner is to the end of the axis, the better it performs. The bigger the polygon overall, the better the scenario represented performs.
The graph on the left shows the strengths and weaknesses of the "Concentrated Growth Full Build" scenario. The polygon is very large: it is at the maximum extent for mode share, demand, and accessibility to jobs, it is a little over halfway extended along the congestion mitigation axis.
The graph on the right shows the "Sprawl Full Build" scenario. The polygon is much smaller: it is nearly fully extended on the demand axis, over halfway out the congestion mitigation axis, only halfway out the accessibility to jobs axis, and about a quarter of the way out for mode share.
