How can we visualize datasets with three variables that are of focus?

a. We cannot generate visualizations based on three variables.
b. We can perform partial visualization on the dataset.
c. We can do it by transforming the data into two variables.
d. We need to resort to a three-dimensional visualization like 3D plotting.

When we have three variables of focus, we can use a three-dimensional visualization technique like 3D plotting to visualize the dataset. This allows us to represent the data in a three-dimensional space, where each variable corresponds to a different axis. By plotting the data points in this 3D space, we can gain insights into the relationships between the three variables and visually analyze patterns or trends.
