The edge-repulsion LinLog model discovers (roughly) the relative geographical locations of the US airports from the airline routing graph. The other two energy models mainly cluster together the hubs in the center of the drawing. In all drawings the airports in Alaska and the South Sea (e.g. Guam) are omitted to improve the readability of the remaining drawing.
