I wonder where this is going and if python+numpy+scipy+matplotlib will one day be replaced by tools written in javascript.
I think it is more likely that some Python library which outputs javascript code in addition to still images will starting to replace matplotlib. Or matplotlib evolves to have that capability itself.
