A system was a handful of ellipses floating in the dark. You could see
that one orbit was bigger than another, but not how big, and not that a
planet sat above or below the plane the others share.
Adds the same plane-and-tether reading aid the outer scales got: a polar
grid in the system's own reference plane, with a drop line from each body
onto it.
Ring radii snap to a 1-2-5 ladder rather than dividing the system evenly,
because the point is to put a number on a distance — 5, 10, 15 AU can be
read at a glance and 4.34, 8.68, 13.02 cannot. That holds across the four
orders of magnitude real systems span: the solar system gets 5 AU rings,
TRAPPIST-1 gets 0.01 AU ones. The outermost ring encloses the outermost
orbit rather than falling just inside it.
The rings are dashed. Solid ones would sit in the same plane as the orbit
ellipses, which are themselves rings, and at a glance a reference circle
and a circular orbit are the same picture. Dashes are cut by dropping
whole segments rather than by a dashed material: the ring is already built
from independent segment pairs, so a material's dash pattern would restart
at every one.
Drawing the grid exposed a framing bug it made unmissable. The camera
settled along one fixed direction derived from the ecliptic, which is
face-on only for the one system whose elements are ecliptic. Every
exoplanet system — measured against the plane of the sky, perpendicular to
the line of sight to its own host star — was being presented nearly
edge-on, a smear of overlapping ellipses. The settle direction is now
taken relative to whichever plane the system was measured in, so all of
them read as discs. The solar system is unmoved, which a test pins.
