| 1. Overall Visualization Goal: Does the result show streamline tubes colored by vorticity magnitude within a rectangular bounding box, similar to the ground truth? | |
| 2. Streamline Clusters: Are there two distinct clusters matches the ground truth layout? | |
| 3. Color Mapping: Are the tubes colored by vorticity magnitude using a blue-white-red diverging colormap, with a similar distribution as the ground truth? | |
