クリップボード内に文字列が入っていれば、いいかえれば「文字列をコピーした状態であれば」、クリップボード内容をテキストとして取り出して文字種別ごとに集計して構成比を円グラフで表示するAppleScriptです。
#  CAUTION: This script process Japanese characters. So, this script make no sense for other language users
グラフ表示部分は手抜きでGoogle Chartsを呼び出しているだけなので、Macがネットワークに接続されていない場合には表示できません。

macOS標準装備のScript Menuに入れて使っています。複数の円グラフを表示させることも可能なので、典型的な例文(新聞、論文、なろう系、技術系文章、文学作品)のグラフを一覧表示して、どの例文の使用比率に近いかといったことを見てわかるようにできそうです(やらないけど)。
ありものをただ引っ張り出してきて、Script文でつないだだけなので、オリジナルで記述した部分はほとんどありません。
とはいえ、技術的にはいろいろなハードルを乗り越えまくって動かしているものでもあります。
・メインスレッドでしか動かせないWkWebView、NSAlertをScriptから呼び出している(実行環境に左右されずに実行)
・Cocoa Scriptingを行うAppleScriptObjCをscript文でscript object化して(カプセル化して)呼び出し、再利用
・WkWebViewをdialog内に表示して、マウスオーバーでデータ内容が見えるようなインタラクティブなグラフを表示
といった、いろいろ無茶なことをやっているScriptです。ただ、すでに見慣れた光景になりつつありますけれども。
