 # Visualize
 
-CodeCarbon provides two ways to visualize your emissions data: a local Python dashboard for offline analysis, and an online web dashboard for cloud-based tracking and team collaboration.
+CodeCarbon provides three ways to visualize your emissions data: a live terminal table while a run is in progress, a local Python dashboard for offline analysis of finished runs, and an online web dashboard for cloud-based tracking and team collaboration.
+
+## Live Terminal View
+
+To watch power, energy and emissions while a run is in progress, add `--live` to the `monitor` command:
+
+``` bash
+codecarbon monitor --live
+```
+
+The table is reprinted on every measurement. It also works with a wrapped command:
+
+``` bash
+codecarbon monitor --live -- python train.py
+```
