I have tried for a responsive design (not always possible when displaying big graphs!), but so far have been concentrating on the desktop 'version'.
This isn't live yet, and is on my self hosting 'server' so if a few people access it simultaneously it may slow down.
Once I have the basic template sorted, I want to rework the graph pages. That is for later.
Feedback welcome.
