Nurture Flows Visualization Mapping Reccomendations

Happy Friday Marketo-ers.

My marketing team is new to Marketo, and new to nurturing. We're building out numerous nurtures - welcome nurtures, thought leadership nurtures, product nurtures, non-responder nurtures, etc. It's an impressive amount of content, and the leadership team is seeing some wins in terms of lead quality.

I'm looking for suggestions about the best way to present an overview of all these interconnected nurtures, along with the number of leads in each program. The primary audience of this document will be my content marketers who create the content in the nurtures; a secondary audience is marketing leadership. Does anyone have insights or templates of nurture maps they can share with me? Thanks in advance.

As an aside, this would be a great feature for Marketo to build - something similar to the campaign canvas in Eloqua, but with programs instead of assets.
