 `%%graph_notebook_config` - Sets the executing notebook's database configuration to the JSON payload provided in the cell body.
 
 `%%graph_notebook_vis_options` - Sets the executing notebook's [vis.js options](https://visjs.github.io/vis-network/docs/network/physics.html) to the JSON payload provided in the cell body.
 
 `%%neptune_ml` - Set of commands to integrate with NeptuneML functionality, as described [here](https://docs.aws.amazon.com/neptune/latest/userguide/notebooks-magics.html#notebooks-line-magics-neptune_ml).

+**TIP** :point_right: `%%sparql`, `%%gremlin`, and `%%oc` share a [suite of common arguments](https://docs.aws.amazon.com/neptune/latest/userguide/notebooks-magics.html#notebook-magics-query-args) that be used to customize the appearance of rendered graphs. Example usage of these arguments can also be found in the sample notebooks under [02-Visualization](https://github.com/aws/graph-notebook/tree/main/src/graph_notebook/notebooks/02-Visualization).
