Visualisation is clearly a key element of design thinking or design-led approach, but there is a pitfall: the visualised material is always just a representation of reality and not reality itself. Once the format of visualisation is fixed, you have to be careful as you might unconsciously distort the fact to fit into the visual.
As the fact is basically always relative, it is almost impossible to capture the reality in a pure form. But still if you turn visualisation as a mean to the purpose of your activity, it could lead you to a wrong direction.
