Qwt graphics in a webpage?

[MattPhillips]

I've seen some threads on using Qt with webpage development, especially this one (http://www.qtcentre.org/threads/20367-qt-gui-application-on-webpage), giving some general pointers about how to put a Qt app on the web. That thread is 5 years old though, and I am wondering if there is anything more to say about the subject, specifically in the context of Qwt objects. Specifically, I want to know if there is a good way to get user-generated Qwt objects on a web-page.

Qwt can serve as a backend for a CGI server producing images that are to be displayed on a webpage. You can also make a browser plugin that uses Qt/Qwt and deploy it on your page but it requires users to download and install it. These are the two most basic possibilities.
