I have a lightweight hack [1] that runs Python in markdown documents and can output basic images/graphs - which is embedded into static pages. The point was being able to write an article that somebody else could see the code behind it and test themselves, e.g. [2]. One of the browsers I test in is Netsurf with JS disabled. Unfortunately it doesn't look great in Lynx.
