One idea I have is a bridge with two supporting columns.
For the purposes of this diagram:
The value of a business has two components: Profits and Risk
Each of those constitutes one column supporting the bridge.
In turn each of those is made up of various smaller components (For example, profits are made from brand, stock, premises etc)
The value of the business is the bridge itself.
There are about 6-10 "components" per column.
I want to give the idea that as either of the columns goes up or down that affects the value of the business.
The bridge was my first idea. Any other suggestions for how this can be represented are welcome.
