I've designed this diagram for my client. But they are not happy with it. It is a really important diagram because it will be used everywhere in their company. They offer three packages to clients: Independent contracting, professional partner and a wrap platform. The difficulty is, they have asked for me to not to assign a colour or image to each of the three business models which makes the job harder.
Are there any diagram, mapping, info graphic sites I can look at for inspiration? Or how would you go about designing this as a graphic designer?
