JSONデータをD3.js + Googleマップに内部配列でインポートする

Question

"Google Maps + D3"（http://bl.ocks.org/mbostock/899711）というD3.jsの例を試しています。サンプルコードでは、外部JSONファイル（stations.json）を使用してデータをインポートします。データを配列でロードすることは可能でしょうか？私は次のようにコードを修正しましたが、うまくいきません。提供されているソリューションをありがとう。

カスタム1での機能を交換し、このようなあなたのローカルデータとすることを呼び出すことができます。

var data = {"KMAE":[.. 
mapFunction(data); 
// Load the station data. When the data comes back, create an overlay. 
function mapFunction(data) {..
