Do you want a graphical floor plan of your home to show what lights are on or off, whether someone is at your doorbell, etc? There are probably lots more ideas to show the status of many things graphically, and to be able to even control them from this view by clicking on the item in the image.
This is a good step-by-step tutorial showing how to put this together. The example showing the layering of the images can be applied to anything else as well.
It does involve many repetitive steps to put it together, but it is certainly not difficult to do. Like most things in Home Assistant, start small with one function, and add to it later on.
