Relation Plots

Relation plots are perfectly suited to showing relationships among variables. A scatter plot visualizes the correlation between two variables for one or multiple groups. Bubble plots can be used to show relationships between three variables. The additional third variable is represented by the dot size. Heatmaps are great for revealing patterns or correlations between two qualitative variables. A correlogram is a perfect visualization for showing the correlation among multiple variables.

Scatter Plot

Scatter plots show data points for two numerical variables, displaying a variable on both axes.

Uses

• You can detect whether a correlation (relationship) exists between two variables.
• They allow you to plot the relationship between multiple groups or categories using different colors.
• A bubble plot, which is a variation of the scatter plot, is an excellent tool for visualizing the correlation of a third variable.
