I set up an example of using the Google Visualisations API at
http://swampstaging.co.uk/uk_singles_chart.htmlThe process for generating this was:
Scrape code from website (ruby+hpricot)
Process code for google's datatable (ruby)
It was a neat way to learn stuff about ruby. programming without a modern IDE is a PITA. i'd forgotten how great resharper+visual studio is. mostly resharper.
