Generating a Visual Site Map of an Existing Site
I thought I could easily answer this question by searching the web, but my Google-fu has failed me. So I turn to you, oh mighty stackoverflowers, and beseech you for enlightenment:

**What is the quickest and best way to generate a visual site map (e.g. flowchart, mind map, IA diagram) of an existing website?**

Additional context: my client has been asked by *their* client to redesign their website. The art directors understandably asked for information on the current site architecture, to which the client had nothing(!). So they have asked me to automagically produce a visual site map by somehow crawling the client's site.

I have found various free/shareware apps that do this, but have been unable to find reviews or best practices. I'd prefer to make a robust recommendation rather than grab the first shareware app that seems to do the trick. So, how would you recommend generating a visual site map?

Much appreciated!
