ポリゴン座標を持つプレースマーカーを含む KML ファイルがあります。json ファイルから読み込んだ値に応じて、その場でポリゴンの塗りつぶしの色を変更したいと思います。私の理解では、Google は kml ファイルをキャッシュしているため、その場でポリゴンの塗りつぶしの色を簡単に変更することはできません。
そのため、Raphael を使用してポリゴンを Google マップに配置できるように、kml ポリゴンを svg パスに変換しようとしています。次に、JavaScriptで塗りつぶしの色を変更できます。
しかし、ポリゴン座標をsvgパスに変換するにはどうすればよいですか?
座標のサンプル セットは次のようになります。
