you can retreive the same chart from Python:
Python 3.1.2 (r312:79147, Oct 9 2010, 00:16:06)
[GCC 4.4.4] on linux2

>>> import urllib.request, urllib.parse
>>> params = urllib.parse.urlencode({'cht':'lc', 'chtt':'This is | my
>>> chart',
... 'chs':'600x200', 'chxt':'x,y', 'chd':'t:40,20,50,20,100'})
>>> chart = urllib.request.urlopen('https://chart.googleapis.com/chart',
... data = params).read()
>>> chartFile = open("chart.png", 'wb')
>>> chartFile.write(chart)

>>> chartFile.close()
