pygraphvizが導入できない

networkxでグラフを作図したいと思い、pygraphvizを導入しようとしましたがエラーが発生しました。

初回に実行したときはMicrosoft Visual C++ 14.0が必要とエラーが出たので、導入後のエラーです。
解決策と、今後同じような状況（エラー発生時やパッケージの導入）に直面した時、どのように
よろしくお願いいたします。

環境：win10

#実行コマンド
pip install pygraphviz

graphviz の本体はインストール済みでしょうか？コンパイルするのに graphviz 本体が必要かと思います。もっと簡単に、pygraphvizをWindows10 64bitでインストールする(Python3) - HYT MachineWorks https://hytmachineworks.hatenablog.com/entry/2019/02/04/001411 本体のダウンロードリンクを探すのに苦労したのでリンクを書いておきます。 https://ci.appveyor.com/project/ellson/graphviz-pl238/builds/32032002/job/92iav81dkovdrv4o/artifacts
