A recreation of E.J. Marey’s graphical train schedule. Stations are separated vertically in proportion to geography; thus, the slope of the line reflects the speed of the train: the steeper the line, the faster the train. This display also reveals when and where limited service trains (in orange) are passed by baby bullets (in red). This type of plot is sometimes called a “stringline chart”.

When flying to the US via Iceland, you never arrive from the East, but always cross the North US border. This two-point equidistant projection focused on Keflavik airport, Iceland (red) and San José airport, USA (blue) demonstrates why.
The circles are great circles centered on either airport spaced at 10° intervals.
The projection implementation is still a work in progress, hence the visual artifacts; it requires elliptical clipping. Based on a gist by Mike Bostock.
