I need to show service availability for a service catalogue I am putting together. I want to do this as economically (in terms of real estate) as possible.
For example, a service may be available:
5am-9am - Emergency Support 9am - 5pm - Core hours 5pm - 9pm - Emergency Support
Was thinking of something like a timeline, but the graphic should fit into a rough square or fat rectangle - i.e. a timeline may be too skinny.
