I recently got a second monitor and needed something to put on it when I wasn't using it, and I was shocked to find that data visualization websites and "web toys" are much rarer than they used to be.
So here's the list of websites I did find, focusing mostly on things that do not require constant input to continue to be interesting, and are web-based, so keep in mind they can go down at any time. (many gotten from a post by Simon Madine, 2012, many contributed by Mr.doob although I have included a selection below.)
