Within a view function you can't print html out, you need to return
the output of the function.

So, using your example, this should give you your graph:

from django.template import loader, Context

def prev_score(request):
graph = graphs.BarGraph('vBar')
graph.values = [380, 150, 260, 310, 430]
myGraph = graph.create()
t = loader.get_template('my_template.html')
c = Context({ 'graph': myGraph })
return HttpResponse(t.render(c))

Have a read through this part of the documentation:
http://docs.djangoproject.com/en/1.1/topics/http/views/#topics-http-views
