はじめに

完全に私的な備忘録です．
LaTeXの作図ツールをtikzを使ってレポートを作成しました．

tikzを使うことにより，画像を張り付ける手間がなくなり，さらに図も綺麗に描けます．

しっかりとした使用方法は理解してないのですが，とりあえず思ったものが綺麗にかけて満足です．

コードと出力結果

コードと出力をペタペタしていきます．

まずは以下をブリアンブルに記載．
(すごい余談なのですが，このブリアンブルって英語で何というんですかね．スペルもわかんない)

\usepackage{tikz} % tikzパッケージを読み込む

コードと出力結果です．(某業界ではおなじみの図表達です)
