The Mercator projection is available as d3.geo.mercator.

Example illustrating zoom and pan with a "rolling" Mercator projection. Drag left-right to rotate projection cylinder, and up-down to translate, clamped by max absolute latitude. Ensures projection always fits properly in viewbox.

The algorithm is:

Create a random DAG (topographically sorted).

Determine X-positions. For each node, find it's minimum X-position. Then, in reverse order, find the maximum X-position of nodes that can be moved forward.

Determine Y-positions. For each node, place it as near as possible to the mean Y-position of its parents. Give preference to placing nodes that have a single parent with a single child (a 1-1 relationship), so that these will always be shown in a straight line.

	Recommend to add aliases in `~/.bashrc` to use this scripts. For example:

	alias cd='. ~/bin/cd-pushd.sh'
	alias d='. ~/bin/dirs-good'
