+You can also include a visualizer embedded in the UI by using the `visualizer` feature:
+
+```
+trunk build --release --features visualizer
+```
+
+This will make the compiled WASM file significantly larger and will impact loading time,
+so it is turned off by default. The visualizer will also only show up on large displays
+(tablets, computer screens), and not on a phone.
