アラートダイアログ上にWkWebViewを配置し、Google Chartsを用いてPie Chartを表示するAppleScriptです。
自分の開発環境（MacBook Pro Retina 2012, Core i7 2.6GHz）で10日間のアクセス履歴を処理して1.38秒程度でダイアログ表示してグラフ描画に入ります。３秒強ぐらいで描画が終了します。
WkWebViewに対して、文字列で組み立てたHTMLを読み込んでグラフ表示しています。Pie Chart上にマウスカーソルを乗せると反応します。一応表示できているぐらいで、デザイン的には余計な余白ができたままで、いまひとつな感じです。せめて、WkWebViewの背景を透明化できると大味な表示をいくらか緩和できるかと思っているのですが、WkWebViewの透明背景にはNSColorではなく（AppleScriptから作成できない）CGColorでclearColor（透明色）を指定する必要があるようで、、、、
サンプル表示データは、Safariの10日間のアクセス履歴からドメイン単位で計算したヒストグラムを、その場で計算したものを使っています。
本Scriptは、①NSAlertのダイアログ表示の経験 ②WkWebView上へのコンテンツ表示の経験 ③グラフ表示用FrameworkやSVGベースのグラフ作成の経験 を経て、２・３年越しで完成したものです。とくに、WkWebViewについてはサンプル数がそれほど多くなく、用途の方向性がObjective-CやSwiftと若干異なるために、参考にできるサンプルの数が多くない状況。必然的に、いろいろ試しては失敗を重ねてきました。急に出来上がってきたものではありません。
Safariの履歴集計ScriptをScriptオブジェクトの中に放り込んだら、scripting additionsの用語をusing terms from句で囲っておく必要がありました。何回か経験していますが、知らないと対処に困る現象です。
現状（macOS 10.14以降）では、Scripting AdditionはmacOS標準搭載のStandard Additionsしか存在していないし認識も行われないため、エラー内容がいまひとつわかりにくく、不正確であるように思えます。Apple純正のStandard Additionsしか存在していないんだから自分で判断しろやコラ、と言いたくなります。
