To visualize datasets with three variables, the best approach is to use three-dimensional visualization techniques. Therefore, the most appropriate response would be:
We need to resort to a three-dimensional visualization like 3D plotting.
This approach allows you to represent each of the three variables on a different axis, providing a comprehensive view of their relationships and interactions. Other methods, such as transforming the data into two variables or partial visualizations, may help to simplify the data, but they won't capture the full complexity of three-variable interactions as effectively as 3D visualizations.
