If you’re watching the results on your Mac, here’s a quick tip:
In Safari, choose a graph or map you’d like to be able to keep an eye on. Choose File > Open in Dashboard… from the menu. Click on the content you want to watch and click Add from the purple bar at the top of the window. You’ll see your dashboard appear and a new widget will load up containing the content of your choice. You can now get back to work and periodically look at the content simply by opening your dashboard (F3 on the latest keyboards, F12 on older ones). You can open as many different items from as many sites as you want this way to create your own custom overview.
If you feel like something is not refreshing as often as you’d like. You can manually refresh it by clicking on it and then pressing Command+R on the keyboard.
The above graphic is the widget I clipped from nytimes.com.
Just did this myself – it is refreshing otomatically [sic]
