将大横页插入文档

Question

我正在尝试将一个大图表插入到我的文档中。图表太大，无法插入到横向 A4 页面中。将单个 A3 或 A2 页面添加到文档的最佳方法是什么？

以下是该文件的概要：

\documentclass[
    a4paper,
    oneside,
    10.5pt,
    fleqn,
    headsepline,
    toc=listofnumbered, 
    bibliography=totocnumbered,
    glossary=totocnumbered,
    abstract=on
    ]{scrartcl}
