import { attribute } from "https://deno.land/x/graphviz@v0.2.1/attribute.ts";
const { rankdir } = attribute;
Sets direction of graph layout. For example, if rankdir="LR", and barring cycles, an edge T -> H; will go from left to right. By default, graphs are laid out from top to bottom.
This attribute also has a side-effect in determining how record nodes are interpreted. See record shapes.
