Modules

charset

Byte-faithful strings and the graph charset (lib/common/input.c, utils.c).

color

Color translation tables, hex/HSV parsing, and SVG color formatting ported from Graphviz 16.1.0 (lib/common/colxlate.c, lib/common/colortbl.h, lib/common/color.h).

diag

Diagnostics as lib/cgraph/agerror.c reports them: agerrorf prints Error: ... and raises the error level that dot’s main returns as its exit status (graphviz_errors + agerrors()), while the layout and the output go on. agwarningf prints Warning: ... and does not change the status.

error

font

Built-in font metrics lookup tables and text/label sizing ported from Graphviz 16.1.0 (lib/common/textspan_lut.c, lib/common/textspan.c, lib/common/ps_font_equiv.h, and lib/common/labels.c).

geom

graph

math

Transcendental functions, called as math::hypot(x, y) the way the C sources call hypot(x, y).
