 This is a collection of packages for working with <a href="https://graphviz.org">Graphviz</a> in JavaScript. The main package, [viz](./packages/viz), is a WebAssembly build of Graphviz with a simple JavaScript wrapper.
 
-With Viz.js, you can easily render a graph written in [Graphviz's DOT language](https://www.graphviz.org/doc/info/lang.html) and display it as an SVG element in a webpage:

 ## Usage
 
-Call `instance()`, which returns a `Promise` that resolves to a new `Viz` instance. Then call any of the instance's `render` methods to render a graph written in [the DOT language](https://www.graphviz.org/doc/info/lang.html). The `renderSVGElement()` method is convenient for displaying a graph in a webpage. The instance can be reused for multiple `render` calls.

A graph can be written in [the DOT language](https://www.graphviz.org/doc/info/lang.html) or as a plain JavaScript object.
