Visually a chart is a 360 degree wheel divided into 12 sections. Each section is named after the famous constellations or zodiac signs that we are all familiar with (i.e Aries, Leo, Gemini, …). Your planets are plotted onto the wheel to see which sign they fall into to. For example, to calculate your Sun sign we look at which zodiac constellation the Sun was sitting in at the time of your birth.
