kotlinでPCにグラフの表示をしたい

前提・実現したいこと

現在kotlinでAndroid開発をしているのですがwav音源を取り込んで、その波形をグラフに変換しようとしています。
当初スマホで表示していたのですがもっと大きい画面で見たいと思い、PCに表示しようとしたのですがAndroidstudioを使ってグラフをPCに大画面で表示する方法がわかりませんでした。
そこでVisual Studio Codeを使ってグラフをPCに表示しようとしたのですがandroi studioでのコードが使えないのかエラーが出てしまいます。
Android studioで仮想デバイスを用いずにPCにグラフを表示する方法、またはVisualstudio codeでのエラーの消し方どちらかでも解決策があれば教えていただきたいです。
