The LossGraphNode creates a visual graph of training loss values over time and displays it as a preview image. It takes loss data from training processes and generates a line chart showing how the loss changes across training steps. The resulting graph includes axis labels and min/max loss values.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `loss` | Loss map from training node. | LOSS_MAP | Yes | - |
| `filename_prefix` | Prefix for the saved loss graph image. (default: "loss_graph") | STRING | Yes | - |

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `ui.images` | The generated loss graph image displayed as a preview. | IMAGE |
