Hi, There's been some discussion about through-the-web data wrangling. I'd not looked at scraperwiki for a while and just found out about their views, e.g. http://scraperwiki.com/docs/python/python_view_guide/ Here's an example view done with HTML/Javascript: http://scraperwikiviews.com/run/hmrc_spending_pie_chart_date_slider/ Seb
