Show me the code that this error resulted

Well, I'm not thecristen, but I too am having a bad time getting this to work. Here's the code:

from django.http import HttpResponse
...
from django.template import RequestContext, loader
from django import forms
from graphos.sources.simple import SimpleDataSource
from graphos.renderers import gchart

...

def do_graph(request):
# get data
data = [
['Year', 'Sales', 'Expenses'],
['2004', 1000, 400],
['2005', 1170, 460],
['2006', 660, 1120],
['2007', 1030, 540]
]
chart = gchart.LineChart(SimpleDataSource(data=data), html_id="Line Chart")
context = RequestContext( request, {'chart':chart.as_html(),'data':data})
template = loader.get_template('s3_numbers/do_graph.html')
return HttpResponse(template.render(context))

my template is basically '{{chart}}' (I also dump the data so that I know the template is actually getting used).

The output? A blank page (with the data dumped below some white space).

Oh, while I'm here I should mention that the tutorial is misleading (or at least, I certainly was unable to copy and paste it - I had to go look at the test code to figure the above out). The tutorial says you can use 'LineChart(...)', which of course doesn't work unless you do something more than the tutorial gives.
