# --------------------------------------------------------------------
# 
# This example generates the same chart as flags-general.py
# But instead of copying from the website, the dataset is queried direcly using jsonp_loader
# The json doc from the url is not in the correct format (lack of quotes), so the sub_d and sub_by parameters
# are used to fix the problem.
