Emoncms.org vs local server?

Hi all,
I assume the link (Mentioned below) is locally installed emoncms but how is it possible for others to access it? also how can I add all these little graphical images to my dash board?
Will be nice if someone direct me to any documentation as I want to have dashboard like this.



One way of ‘exposing your emoncms’ could be as explained at Remote Access - Guide | OpenEnergyMonitor
