Google Visualization API―データを操作する - 愚鈍人. 本稿ではGoogle Visualization API の英文のドキュメント中にVisualizationと記述されている語をわかり易いようにチャートと呼ぶことにする。
例えばTable visualizationはテーブルチャートと記述する。 チャートだけでなくチャートの基となるデータの操作についてもGoogle Visualization APIは非常に高機能だ。 Google Visualization APIのチャートの基となるデータはDataTableに格納される。 DataTableはリレーショナルデータベースのテーブルと同様に２次元テーブルで表現される。 またチャートの基となるデータには他に、読み込み専用のDataViewがある。 DataTableとDataViewの関係は一般的なリレーショナルデータベースのTableとViewの関係と同じようなものと考えられる。 DataViewは、基となる書き換え可能なDataTableから特定の列や行，フィルタリングされたデータを抽出してつくられた読み込み専用のテーブルということになる。 DataTable DataTableを作成し、データを格納するには２つの方法がある。 DataTableオブジェクトを作成してデータを格納するには以下の例のようにする。 以下のようにオブジェクト作成時に格納するテータも同時に指定する事もできる。 DataTableクラスのコンストラクタの第一引数にテーブルの内容を示すJSONデータを，第２引数にワイヤープロトコルというデータフォーマットのバージョンを示す数値を指定する。 Web, Perl/CGI & jQuery/AJAX. Ajax. Description: Perform an asynchronous HTTP (Ajax) request.
The $.ajax() function underlies all Ajax requests sent by jQuery. It is often unnecessary to directly call this function, as several higher-level alternatives like $.get() and .load() are available and are easier to use. If less common options are required, though, $.ajax() can be used more flexibly.
At its simplest, the $.ajax() function can be called with no arguments: Note: Default settings can be set globally by using the $.ajaxSetup() function. This example, using no options, loads the contents of the current page, but does nothing with the result. The jqXHR Object The jQuery XMLHttpRequest (jqXHR) object returned by $.ajax() as of jQuery 1.5 is a superset of the browser's native XMLHttpRequest object.
As of jQuery 1.5.1, the jqXHR object also contains the overrideMimeType() method (it was available in jQuery 1.4.x, as well, but was temporarily removed in jQuery 1.5).

Visualization. Data::Google::Visualization::DataTable - Easily create Google DataTable objects version 0.10 Easily create Google DataTable objects without worrying too much about typed data Google's excellent Visualization suite requires you to format your Javascript data very carefully.
It's entirely possible to do this by hand, especially with the help of the most excellent JSON::XS but it's a bit fiddly, largely because Perl doesn't natively support data types and Google's API accepts a super-set of JSON - see "JSON vs Javascript" below. This module is attempts to hide the gory details of preparing your data before sending it to a JSON serializer - more specifically, hiding some of the hoops that have to be jump through for making sure your data serializes to the right data types.
