Layout engines

All eight Graphviz layout engines are registered. Pass the engine name as the second argument to renderSvg:

renderSvg(dot, 'neato');

Engine	Layout style
dot	Hierarchical / layered directed graphs
neato	Spring-model (Kamada–Kawai)
fdp	Force-directed
sfdp	Multiscale force-directed (large graphs)
circo	Circular
twopi	Radial
osage	Clustered
patchwork	Squarified treemap

Fidelity note

Engines split into two conformance classes (see Conformance for the exact definition and comparison code):

• Deterministic — dot, circo, twopi, osage, patchwork. Held to the same ±0.01 bar: numeric coordinates and paths agree with the native C binary within ±0.01pt and all non-numeric content (tags, colors, text) is exactly equal on the golden corpus.
• Iterative — neato, fdp, sfdp. Force-directed/multiscale solvers that depend on floating-point rounding order, so they are checked at a looser ±0.5pt bound and for structural (same element tree) agreement rather than tight numeric equality.

Neither bar is a claim of literal byte-for-byte SVG output. For current pass counts and any accepted divergences per engine, see Parity (with per-engine detail pages) and Known divergences.
