It load some of the page, but not the map or any of the graphs.
I’m getting the same with darksky but also trying to use Datadog dashboards some elements don’t display.
I think it’s because they are WebGL and it seems that isn’t supported in the screenly browser:

Further digging suggests it might be available in the web engine but disabled?
upgrading to experimental enabled WebGL but didn’t fix Datadog or darksky for me 
But https://wpewebkit.org can display these pages so the pi is capable (in hardware at least)…
At the time, the browser the player used could not handle the WebGL maps and graphs on pages like that. The app now uses a modern browser engine (the same one behind Chrome) with working WebGL, so complex dashboards render properly. Note that darksky.net itself was shut down a while ago, so that specific page will not load anywhere now, but pages of that kind work. Marking this as solved. If a particular dashboard still will not render on a current version, share the link and we will take a look.
