if you want to offer lots of properties one can change, POST via ajax is the
better way - as you said
long URLs can get very ugly - although you could shorten them like youtube
or others do it.
GET is far better at this point of time, as only GET requests are cachable
(as far as I know) by djangos
middleware.
if I understand you right: you want to mix html with image-data? That is
impossible. But you can
add parameters to the header of the http response of the image and put in
there all settings needed to render the image...
So you need 2 urls - although you could add a second variable to the url
e.g. output:
url(r'^graph_example/(?P<id>\d+)/(?P<output>\w+)/$')
and then a view:
def myview(request, id, output):
if output == 'image':
# output image data
else:
# output html data
