import { attribute } from "https://deno.land/x/graphviz@v0.2.1/attribute.ts";
const { charset } = attribute;
Specifies the character encoding used when interpreting string input as a text label. The default value is "UTF-8". The other legal value is "iso-8859-1" or, equivalently, "Latin1". The charset attribute is case-insensitive. Note that if the character encoding used in the input does not match the charset value, the resulting output may be very strange.
