Bearing and Distance Calculator (C) 2025 Sudrien MIT

Calculates the bearing between two sets of longitude and latitude. Will also give a distance as a percentage of equatorial length.

If given a planet size (Earth, Moon and Sun have preset buttons) The distance will be a km/Mm measurement.

Also gives a preview of the direction and distance. Still trying to figure out the best projection.

Uses d3/d3 and d3/d3-geo-projection
