Type Alias VizEngine

The Graphviz engine surface jssm/viz actually consumes: one ready-to-use object with a renderString(dot, options) method. This is the contract for configure({ viz }) injection — a direct adapter, not a factory: the caller instantiates (and, if needed, awaits) their engine themselves, then hands over the finished object. renderString receives the dot source and an options object whose members jssm/viz uses are format (always 'svg') and engine (a Graphviz layout engine name, when the caller of a render function supplied one); it may return the output string synchronously (like @viz-js/viz) or as a promise (like asm.js viz.js 2.x), and jssm/viz awaits either.

import { instance } from '@viz-js/viz';
configure({ viz: await instance() });   // the default engine, injected by hand
