Why It Works
The simplicity of this map makes it effective. A dark imagery basemap provides an ideal backdrop for striking bright green view lines. The thin view lines are partially transparent. En masse, the density of lines nearest the UK coastline appear as a bright glow. As longer view lines travel farther, they appear more subdued. Curving lines show the power of map projections. Although the information about this map is very much global in nature, it would have less appeal in 3D. Instead, swooping curves on a familiar Mercator projection work to reveal surprises.
