I've started getting involved in reviewing questions and answers on Stack Overflow and came across a question which already had 2 close votes.
I read the question, and felt it was a good fit (asking about libraries to achieve to render a visualization on the web), and happen to know about the area. I've been watching it and it's since received another 2 close votes but I can't understand why.
I wanted to get other people's views on the question, and try and understand why questions that perfectly fit the FAQ are being marked for closing?
The FAQ specifically suggests questions on "software tools commonly used by programmers" fit the site, and at least one of the answers (D3) has it's own reasonably popular tag on SO.
