how to create real-time web pages with web2py ?

for example, I can display the user register numbers in a web page, or 

I can update a chart periodically to get a real-time effect by using a timer to insert the new data in the plot and redraw it.

Hi!!!.

In the next link http://www.web2pyslices.com/slice/show/1335/client-tools-for-web2py, there is an example about a timer. Example

This will call a server function once after 5 seconds:

def index():
    callback = js.call_function(handle_it)
    page.ready(js.delay(callback, 5000))
    return dict()
def handle_it():
    return js.alert("Gotcha!")

Greetings.
