Architecture is often seen as dusty overhead or outdated modeling. To overcome such feelings architects needs to involve stakeholders a lot. They also have to communicate in a clear way using terms of the business to make their point.
Visualization can help a lot in communicating architecture. However, not all ways of modeling are sufficient. Transforming abstract thought into graphic is a complex process. In search for input for developing good methods I stumbled upon A Periodic Table of Visualization Methods. All kind of methods are shown, like data visualization, information visualization, concept visualization, strategy visualization, metaphor visualization and compound visualization. It gives a very nice overview view of all kind of visualization methods, really a must see!
