The Yahoo! Pick of the Day for May 30, 2002 was censusscope, a site providing public access to maps and charts based on US census data. One of the developers, Bill Abresch, writes:
Today's Yahoo! Pick (http://picks.yahoo.com) was constructed using PLT Scheme and Oleg Kiselyov's SXML->HTML. (Charts and maps were made with other tools, but Scheme was used to turn these raw materials into a web site.) The ease of development has been extraordinary.
Thanks for the great tool,
Bill
