Worth a Thousand Words
Use an SVG graphic widget on your next Node-RED project to get a visual representation of your automation setup.
There are some great components for showing tables, gauges, and charts on Internet of Things (IoT) dashboards.

Figure 1 is an example of a process automation screen that could be used for an industrial control system.
