This example shows a shell command that forcefully terminates every running Airflow task by killing their processes. It first displays the command, then explains its mechanism: `ps aux` lists all system processes, `grep "airflow run"` filters for Airflow task executions, `grep -v grep` removes the grep process itself, `awk '{print $2}'` extracts process IDs, and `xargs kill -9` sends a forceful termination signal. The code relies on standard Unix utilities—`ps`, `grep`, `awk`, and `xargs`—rather than a visualization library, presenting the operation as a text-based data flow.
