A draconic chart takes an ordinary birth chart and spins the whole zodiac until the Moon's north node sits at 0° Aries.

Everything keeps its relationship to everything else and only the sign positions change, so it is a re-framing rather than new data. Practitioners read it as the chart of what somebody intends as opposed to what they do, and compare the two. The technique dates from the twentieth century, though the node it is built on does not.
