Problem 4: Restart and Run All to Verify Reproducibility

Problem Description

Build a small 4-cell notebook performing a simple data loading and plotting task, then use "Restart Kernel and Run All" to confirm every cell runs successfully from a completely clean state, with no leftover variables from prior experimentation.

Input

None (structure the notebook with any simple data + plot task).

Output

Confirmation that all cells execute successfully, top to bottom, from a clean kernel restart.

Constraints

• At least 4 cells, including one that creates data and one that plots it.

Example Input

text
(No external input needed)

Example Output

text
(All cells execute without error after Restart Kernel and Run All, confirming the notebook is fully reproducible)

Concepts Covered

Kernel restart, reproducibility verification.
