Definitely, although the New York Times develops a lot more than other newspapers do: http://open.blogs.nytimes.com/category/interactive/

They are one of the few newspapers that can possibly afford it, I guess.

Definitely the best I've seen in any online news media websites.

Their election tracker and real-time update of votes in the primaries were very well done.

Even the summary after the vote looks neat:

After some digging, found out they have open-sourced this library:

I also really enjoyed the presentation of the information. The information was presented gradually in an easily digestible format.
