How can I organize my logged charts and media in the W&B UI?

The / character separates logged panels in the W&B UI. By default, the segment of the logged item's name before the / defines a group of panels known as a "Panel Section."

wandb.log({"val/loss": 1.1, "val/acc": 0.3})
wandb.log({"train/loss": 0.1, "train/acc": 0.94})

In the Workspace settings, adjust the grouping of panels based on either the first segment or all segments separated by /.
