Generating graphs of websites (Crawling + Graph visualization)

We would like to ask who of you can generate quickly beautiful graphs of websites showing all (main) relations in a website? The idea: - Crawl a website and extract the main relations - Show the relations by graph visualization software - Automate the process such that the (human) time involved is minimal An example is shown in the attachment. Pay special attention to: - Websites may contain > 1.000.000 links, filter the main relations from the 'not-so-important' relations - Required depth of levels is approximately 5 and links to external website may be visualized, but external websites themselves do not have to be crawled. - Generate (automated) graphs (without hand manipulation, except predefined filters) for [login to view URL], [login to view URL], [login to view URL] - Explain how to regenerate the graph. So make sure it is fully automated or according to a procedure. Write down this procedure, step by step. We will ask three parties to work on this. The one who generates the easiest (automated, with clear procedure), an insightful and good-looking graph get's a 100 dollar bonus. Thanks for your bids!
