(Suggested by @mbostock)

either by having a variable color for LineString (seems hard), or an option for Plot.line (or maybe a curve?) that follows spherical line interpolation.

Plot.line(beagle.coordinates, {stroke: (d, i) => i, z: null, strokeWidth: 2})
untitled (71)

SOLVED WITH curve: "projected"

I like the idea of an option to Plot.line that allows spherical interpolation between points.

I haven't yet found how to avoid the special-case (we need to skip the projection and maintain spherical coordinates until the geoPath).

* curve: "geodesic" for Plot.line

closes #1146

* Line handles the "sphere" curve to follow great circles on spherical projections.

* fix filtering, input normalization

* Update README

* curve: "projection"
