import { attribute } from "https://deno.land/x/graphviz@v0.2.1/attribute.ts";
const { samplepoints } = attribute;
If the input graph defines the vertices attribute, and output is dot or xdot, this gives the number of points used for a node whose shape is a circle or ellipse. It plays the same role in neato, when adjusting the layout to avoid overlapping nodes, and in image maps.
