On a 3D globe (layout.geo.projection.type: 'globe3d'), how high each segment of the line rises above the surface in its middle: globe radii per radian of the segment's length, so a long route stands clear of the globe and a short hop stays low. 0 keeps the line on the surface. Values above 1/π (an arc to the antipode one radius high) are drawn as 1/π. The line of a filled trace (fill: 'toself') stays on the surface. A Holochart extra (Plotly has neither the globe nor this attribute); ignored on a flat projection. Minimum: 0
