+Please note that the replay uses the same schema as initially deduced from the input. You therefore need to perform the date parsing again:
+
+```python
+data = data.with_columns(t=data.t.dt.utc_from_timestamp(unit="ms"))
+```

 Since your task here is to create a dashboard, you no longer need to display intermediate tables. Therefore, you can remove the empty `data` statement at the end of the data loading cell. Similarly, you can comment out or remove the data printing statements at the end of every other cells.
 
 As promised, you can use the code designed for static data with streaming data.
