This refers to a style of chart wheel, sometimes known
as an ‘unequal wheel’. It places the planets and houses against a 360° wheel,
allowing the span of each house to be unequal (and therefore having the
disadvantage of bunching up collections of planets) but allows aspects to be
read with ease. The alternative makes each house the same size and allows an
easy identification of a planet’s house position, but aspects between the
planets are less easy to identify as zodiacal measurement is distorted.
