The Bodygraph
Also known as: Human Design chart · rave chart
The bodygraph is Human Design's chart: nine geometric centers connected by channels, showing exactly where your energy is defined, open, and connected.

What you're looking at
The bodygraph is the map itself — the diagram everything in Human Design is read from. Nine geometric shapes (the centers) sit in a rough figure of a human body, joined by a lattice of lines (the channels), each made of two halves (the gates). When your birth calculation activates both gates of a channel, that channel completes, and the centers at both ends become defined — colored in, fixed, reliably yours.
Everything else stays white: open. An open center isn't broken or empty — it's where you take in the world, feel other people intensely, and over a lifetime, grow wise about what you're feeling. The colored-versus-white pattern is the chart's first and most important sentence.
How to read one, in order
Start with the big picture: which centers are colored? That pattern determines your type — the Sacral defined makes you a Generator or Manifesting Generator; a motor connected to the Throat without a defined Sacral makes a Manifestor; and so on. Then find your authority: the highest-priority defined center in a fixed hierarchy, which names the part of your body designed to know what's correct for you.
Then the detail: the numbers around the outside are your gate activations — black for the conscious Personality side, red for the unconscious Design side, calculated roughly 88 days apart. The two numbers at the top of each column give your profile. A practiced eye reads a bodygraph like a face; a beginner needs only the first two steps to start experimenting.
Why ours looks the way it does
Every bodygraph shows the same mechanics, but not every bodygraph is drawn with the same care. We render yours from precise astronomical data — the JPL DE440 ephemeris, with historical timezone rules applied to your birth place and era — because a chart is only as honest as its calculation.
Then we make it beautiful, because we think a map of how you're built deserves to be an object you want to keep, not a screenshot you lose in your camera roll.
Questions people ask
- What do the colors in a bodygraph mean?
- Colored (defined) centers are fixed, consistent energies you carry your whole life. White (open) centers are where you receive and amplify other people's energy — areas of sensitivity, learning, and potential wisdom.
- What's the difference between the red and black numbers?
- Black numbers are your Personality — the conscious side, calculated at your birth moment. Red numbers are your Design — the unconscious side, calculated about 88 days before birth. You'll recognise yourself in the black; people who know you well recognise you in the red.
- Is a bodygraph the same as a natal chart?
- No. A natal chart is astrology's wheel of planets in signs and houses. The bodygraph maps those same planetary positions onto the I Ching's 64 gates and nine centers — a different structure with different outputs.
- Why do some charts look almost empty?
- Charts vary from a single defined channel to nearly full definition. Fewer defined centers doesn't mean less of a person — Reflectors, with no defined centers at all, are the system's rarest and most environmentally attuned type.

Human Design is a system of self-reflection that maps how your energy is designed to move, calculated from the exact time and place you were born.
GatesGates are the 64 activation points of the bodygraph, one for each I Ching hexagram, switched on by the planets' positions at and before your birth.
ChannelsChannels are the 36 connections of the bodygraph — each completed when its two gates are both active, defining the centers at either end for life.
Single DefinitionSingle definition means every defined centre in your chart connects in one continuous circuit — self-contained energy that processes quickly and consistently.
The ReflectorReflectors have no defined centres at all: the rarest type, mirroring the health of their environment and finding clarity over a lunar cycle of about 28 days.
