Landscape map viewpoint
The landscape map viewpoint as a visualisation good for articulating a portfolio using three dimensions on the x-axis, y-axis and colour-coding. They can show the health of the portfolio clearly: if there is a high concentration of elements within a particular cell, then it’s typically a sign that there is redundancy; conversely if an element covers too much of the table it could be over-extended. The colour-coding speaks for itself. Knowing your domain, you will know shapes and patterns are acceptable or not.
