Right now the easiest way to put it in the sidebar is to modify your
theme. You can add the following snippet of PHP to your sidebar in
your theme and it will show a sparkline for that page:
$data = new GADWidgetData();
echo $data->gadpageviewssparkline(substr($SERVER["REQUESTURI"], -20));
There are other options as well but you would need to look at the code
to find them. I've got embedding it in the sidebar on my todo list but
I just haven't had the time to get to it yet.
