I don’t know that any of the desktop browsers do support it yet.

Certainly it’s not implemented in Squiggle.

Yes that’d be because the browsers don’t support that #element yet.

The syntax needs to be:

  file:/Users/jonathanchetwynd/Desktop/weather.svg#svgView(viewBox(0,0,200,200))

I know that SVG view specifications like that will work in Batik and
Opera.

With the simple #element syntax (which isn’t implemented widely yet),
you need to have an ID on your <use> element because that’s where the
graphical content is placed.  The <symbol> is just a definition to
re-use.  If you had two <use> elements that used the same symbol, then
you need some way to identify which of those two <use>s you want the
initial view to be zoomed to.
