| Visual | List of possible visualizations, Feature Distribution or Feature Correlation. |
| Segment | <p>- Selecting a saved segment<br>- Defining an applied (on the fly) segment. This applied segment isn’t saved (unless specifically required by the user) and is applied for analysis purposes.</p> |
| Feature | <p>- Feature Distribution: Select a single column of a supported data type to view the distribution of its values<br>- Feature Correlation: Select two columns to visualize their correlation<br>- Correlation Matrix: Select up to eight columns to visualize their pairwise correlations</p> |

Histogram
Categorical and boolean value may only be displayed as Histograms, but other column types may also be displayed as such.
Displays for Feature Correlation
Line Plot
Scatter Plot
Stacked Bar Plot
Box Plot
