This shows a rich Web UI, that can be served by a small machine (like a Raspberry pi Zero). The small machine provides the
data, the data UI is rendered on another device, connected on the same network as the small machine (possibly emitted by it).
The UI rendering is the most demanding process, taken care of by a phone, tablet, or laptop, connected on the network, and not by the server itself.
This brings us back to this Entropy Zero (EZ) computing paradigm. Network, but no Internet. Not cloud. Flake Computing.
