Overview

Body diagrams annotate a human figure by muscle name. Name the muscles that matter, color them with a tag group, and add a short note beneath each — the rest of the figure stays a neutral gray so the highlighted muscles read at a glance. Reach for body for workout splits, PT / rehab and injury reports, and anatomy teaching. It is a labeling surface, not a data chart: there are no axes and no values, just a figure and the parts you call out.

The layout is automatic. Muscles you name are filled and given a gutter label with a leader line; a legend maps each tag color to its meaning.

When to use

• body — you are labeling parts of a person, and the underlying picture needs to be a human figure.
• map — you are labeling parts of the Earth rather than parts of a person.
• block — the surface is an arrangement you define yourself, not a fixed anatomical figure.

Syntax

body Title
muscle
front

<muscle name>  <tag>: <Value>
  <note>

A body file is a header line, a few optional bare figure directives, an optional tag group, and then one part line per muscle you want to call out. A part line is just a catalog muscle name, with optional trailing tag metadata and an indented note.

Figure: form, sex, view

Four figures ship — male and female, front and back. Set the figure with bare directives before the parts; each is optional and defaults sensibly:

body Back & Legs
muscle
female
back

lats
hamstring
glutes

skin renders any figure as a plain silhouette (head + hair, no muscle segmentation) — useful when you only want to point at a region. skeletal is reserved.

Two views at once

Name both front and back to render the two views side by side in one diagram. A part is drawn on whichever view(s) contain it — chest on front, lats on back, deltoids / calves on both:

body Full Body — Front & Back
muscle
front
back

chest
lats
quadriceps
hamstring
calves

Parts

A bare line is a catalog name for the active figure. Order does not matter — the figure is fixed; you are just choosing what to light up. Which names are valid depends on the view (front vs back). An unknown name emits a warning and is skipped; the rest of the diagram still renders.

Muscles (muscle form)

Full catalog by region. F = available on the front view, B = on the back view. Bare names are the primary catalog entries; the fine heads in the last column are separate names for the individual heads where the art splits them.

Surface landmarks (skin form)

In skin form you can also point at surface features — leader-only dots, no fill:

Aliases

Names accept gym shorthand, formal anatomy, or plain-English surface words — all resolve to the same catalog entry:

body Gym Shorthand
muscle
front

pecs
delts
quads

Left / right

Prefix any part with left or right to call out one side only (the figure’s own anatomical side — on a front view right is the pec on the left of the image). It scopes both the fill and the leader, so a one-sided injury highlights one side alone. Works on muscles and surface landmarks.

body Injury Report
skin

tag Status as s
  Torn red
  Sore orange

right pec    s: Torn
  Bench tear
left biceps  s: Sore
right knee   s: Sore

Tags & Color

Muscles are gray until you tag them. Declare a tag <Facet> as <alias> with a distinct color per value, then apply it to a part with <alias>: <Value>. The tag colors the highlighted muscle, its leader line, and its label, and adds a labeled legend entry:

body Boarding-Party Wounds
muscle
front

tag Severity as s
  Critical red
  Moderate orange
  Watch yellow

deltoids   s: Critical
  Musket ball, left shoulder — immobilize
obliques   s: Moderate
  Cutlass graze
forearm    s: Watch
  Rope burn, both hands

Notes

A bare indented line beneath a part is a note (the same shape as a pyramid or ring note). The first note prints beneath that muscle’s gutter label — use it for the exercise, the set/rep scheme, or the clinical finding.

Options

• no-legend — hide the tag legend.
• no-title — hide the title line.
• fill-tint | fill-solid | fill-outline — fill treatment for the highlighted muscles. Mutually exclusive; the last one written wins.

Appearance

Body accepts these universal appearance directives:

Colors come from the active palette — see Colors. Set the palette and light/dark theme at render time with --palette <name> and --theme light|dark|transparent.
