In astrology, a Natal Chart Wheel is the circular diagram used to display the structure of a natal chart. The wheel typically shows the twelve zodiac signs around its outer framework, the twelve houses within the chart, and the calculated positions of planets, angles, and other chart factors. Aspect lines may also be drawn across the interior to show angular relationships among chart factors. The Natal Chart Wheel provides a visual map of the chart’s structure, allowing its many components to be viewed together before they are interpreted in greater depth.
