How to effectively visualize an Application Landscape in Enterprise Architecture

In enterprise & solution architecture, connecting boxes with arrows is an often used and overrated visualization from high-level, thru component architecture, down to data and class diagrams. However, to create a holistic view on systems, component diagrams are not enough! When it comes to analysis or transformation of a high-level application- or service-architecture, I prefer to draw an Application Landscape Diagram, which I would like to show and elaborate on in this post.
