Open Flash Chart 2 not showing in Ruby on Rails

Question

My question is about my first Open Flash Chart not displaying at all in my Rails application (2.3.5 running on Vista). I am trying to implement: http://openflashchart2.heroku.com/chart_examples/pie. All the code is in but when I load the view using the server, there's nothing there! Pull up the blank page's source code and I see:

    swfobject.embedSWF(
    "/open-flash-chart.swf","flashcontent_4000",
    "650", "300", "9.0.0", "expressInstall.swf",
    {"data-file":"/charts_ofc2%2Fpie"}, {{}}, {{}} );

but I do NOT see anything like this (this is copied from the source code of the example page):

    <object type="application/x-shockwave-flash" wmode="transparent"
    data="/open-flash-chart.swf" width="650" height="400"
    id="flashcontent_108400" style="visibility: visible; ">
    <param name="flashvars" value="data-file=http%3A%2F%2Fopenflashchart2.heroku.com%2Fcharts_ofc2%2Fpie"></object>

I think the lack of this chunk is why I'm not seeing the graph. Do you know where the problem is? Thank you so much.
