I am trying to insert a large diagram to my document. The diagram is too large to be inserted to a horizontal A4 page. What is the best way to add a single A3 or A2 page to a document?
This is the outline of the document:
\documentclass[
a4paper,
oneside,
10.5pt,
fleqn,
headsepline,
toc=listofnumbered,
bibliography=totocnumbered,
glossary=totocnumbered,
abstract=on
]{scrartcl}
