Creating a chart similar to the google analytics funnel

I'd like to create a page which does what the google analytics 开发者_JS百科funnel does, but using data from our own system.

Unfortunately it seems that the funnel isnt exposed in the google charts API, or perhaps it's called something else? I guess the real value here is not the funnel itself, but all the extra data they put on the page. So; I Wondered if there was some tool that would render all that together? Or should I just simply create the page from component parts?

Here is a link to a typical funnel:

You need to use the Google Analytics Management API to make a Goal Feed Request -

The goal feed provides a quick way to access all the configured goal information for a particular profile. This feed is important because it provides access to goal names, goal types, and goal status (active or inactive). The goal feed is a child of a Profile Feed Entry.
