You haven't defined where in the admin interface you want this image to be
displayed? A table?
I have not tried this, but could you not create an additional field on your
model that returns the HTML-encoding needed to display the SVG?
E.g.
class MyModel():
svg_text = CharField()
def _the_svg(self):
return """<svg width="100" height="100">%s</svg>""" % self.svg_text
_the_svg.allow_tags = True
I am not sure about editing visually, however - I would expect that would
require a specialised widget.
