+ # The following pertain to caching and accessing Gruff graphs
+ # To make caching easier, add a line like this to config/routes.rb:
+ # map.graph "graph/:action/:id/image.png", :controller => "graph"
+ #
+ # Then reference it with the named route:
+ # image_tag graph_url(:action => 'show', :id => 42)
