d3-cloudを用いてワードクラウドを表示するAppleScriptです。
本AppleScriptでは、
{|word|:"NSString", |count|:97}
のように、登場単語、登場回数のように集計ずみのデータをJSONに変換してワードクラウド表示させています。この（AppleScriptの予約語にかぶりまくりな）属性ラベルはd3-cloud側の仕様です。
以前に作った「Tag CloudっぽいRTFの作成」のデータを用いて（属性ラベルを置換して）表示させたものがこちら（↑）。
Tag/Word Cloud関連のJavaScriptについては前から気になって調べてはいたのですが、「ローカルにデータを持つスクリプトが多い」「d3-cloud自体をローカルにインストールさせる例が多い」（実行速度などの問題で？）という状況で、ありもののスクリプトをこのアラートダイアログ上にはりつけたWkWebViewの「箱庭環境」で追加スクリプトのインストールなしで動くように書き換えるのに少々手間取りました。
CDNにホスティングされているd3-cloudを呼び出すことで、ローカルにd3-cloudをインストールせずに実行していますが、将来的にこれが変更・廃止された場合には別のWeb上のどこかにホスティングされているd3-cloudを呼び出すことになります。
ローカルにあるテキストコンテンツ（CotEditorで編集中の文章とか、Pagesで作成中のワープロ文章とか、Keynoteで作成中のプレゼン資料の内容とか）を分析して頻出単語を取り出し、タグクラウドといいますかワードクラウドで表示して全体の見通しをつけるというScriptは作りたいと思っていました。
