For me it doesn't sound safe if you're going to update data with 5m
interval. E.g. see ticket #13988 [1].
How about embedding/redirecting to the Atlas page or writing your custom
plotter/page that fetches data from Onionoo? It should be safe since
this data is collected in a way to preserve anonymity of Tor users. If
it doesn't prevent anonymity degradation it can be fixed. And when it
got fixed I is fixed for everybody.
I'm sure it's not a good idea to do your own statistics and you should
rely on what tor collects.
