6 2D Visualization and insight

 

This chapter covers

  • The importance of visualization in digital twins
  • 2D visualization techniques
  • Building effective visualizations of the digital system
  • Building dashboards with off-the-shelf software

The digital representation of a physical system built from sensor data, external systems, and existing artifacts often operates behind the scenes. In many digital twins, this representation functions without requiring a visual interface at all, supporting automated analysis, simulation, or control processes.

When visual interfaces are introduced, they make the twin accessible to human users. Physical systems can be represented digitally in 2D through diagrams, schematics, geospatial views, floor plans, and data dashboards. These visualizations translate complex data into forms that people can quickly interpret. By condensing large volumes of data into intuitive visual structures, they help bridge the gap between computational processes and human understanding, allowing users to interpret system behavior and make informed decisions when needed.
