Yes. My understanding is svg-web is mostly a hack to wrap the XML of
SVG in a script tag so that the script can make it work in Microsoft's
joke browsers. Just get rid of the <script> tag, maybe add <!doctype
html> at the top, and their examples of SVG in HTML should work fine
in decent browsers without that overhead.

1) You should be able to inject new SVG by manipulating the DOM,
thereby changing the SVG and making new stuff appear. svg-web
includes some DOM manipulation but so do other JS toolkits.
2) There is limited animation capability in SVG+SMIL (careful many of
the examples on the Web are stuck using the Adobe syntax for embedding
SVG).
http://www.kevlindev.com/tutorials/basics/index.htm is a nice intro to
both techniques.
3) There are also weird mutants like
http://hacks.mozilla.org/2009/06/rendering-svg-canvas-burst/ , where
as I understand it the Burst JavaScript framework can read in
fragments of drawings from SVG files and then animate them on a
canvas. E.g. <http://hyper-metrix.com/burst/development/doc/demos/js/GitHub%27s-Octocat.htm>
Lots of ways to do it!
<https://www.svgopen.org/2009/papers/54-SVG_vs_Canvas_on_Trivial_Drawing_Application/>
is a paper that tries to compare canvas and SVG, but there's no
definitive answer.
