[web2py] web2py pygal graph

[kecajkecaj123]

Hi Guys, 

Trying to draw some graphs using pygal and below link:
http://www.web2pyslices.com/slice/show/1634/beauty-graphics-and-charts-with-pygal

It works fine, but my view display only graph, without anything else 
included in the view e.g. headers, styling etc.

Controller:

def graph():
        response.view = 'default/graph.html'
        response.headers['Content-Type']='image/svg+xml'
        dateline = pygal.DateLine(x_label_rotation=25)
        dateline.x_labels = [
        datetime.date(2013, 1, 1),
        datetime.date(2013, 7, 1),
        datetime.date(2014, 1, 1),
        datetime.date(2014, 7, 1),
        datetime.date(2015, 1, 1),
        datetime.date(2015, 7, 1)
        ]


        dateline.add("Serie", [
        (datetime.date(2013, 1, 2), 213),
        (datetime.date(2013, 8, 2), 281),
        (datetime.date(2014, 12, 7), 198),
        (datetime.date(2015, 3, 21), 120)
        ])
        
        return dateline.render()


view:

{{extend 'layout.html'}}


<h1>MY FIRST GRAPH</h1>


<embed src="http://localhost/project/default/graph.svg"; type="image/svg+xml" 
/>


How can i disply my original view containing styles from layout.html, 
header "MY FIRST GRAPH" and the graph itself? 

Thanks
