Public graphs can be framed from /embed/g/[slug]. Replace the slug with the live graph path.
<iframe src="https://graf.ink/embed/g/your-slug" title="Graf.ink graph" loading="lazy" style="width:100%;height:640px;border:0" ></iframe>
An embed shows the live graph, including its sources and the Graf.ink name. Do not strip the sources or present the graph as your own work. Keep the iframe title so people know where it came from.
Open a public graph, copy its slug, and use that slug in the address above. Organisation licences are not offered yet. A contact address will be published here when the owner supplies one.
