Natal wheel
The natal wheel is the familiar circular diagram of a birth chart. The rim is divided into twelve zodiac-signs segments; houses cusps slice the circle; planet glyphs mark ecliptic longitudes. The left horizon (9 o'clock in many graphics) is the ascendant; the top is often the midheaven.
Wheels make pattern recognition easy: stelliums (chart-patterns), hemispheres emphasis, and aspect lines stand out at a glance. The same data can be delivered as JSON or SVG from west.wheel_graph without changing the astronomy — only presentation changes.
On the wheel, notice
- Angles and lights — ascendant, midheaven, sun, moon
- Occupied houses versus empty sectors
- Aspect lines — majors first (aspects, orbs)
- Retrograde marks — retrogrades
Comparisons
Synastry bi-wheels place one natal-chart inside another so inter-chart aspects are visible around the shared center. Follow wheel-reading-order for single-chart sequence; see overview for all topics.
