Multivariate Visualization for Economic Data
Multivariate visualization allows you to explore the relationships among several economic variables at once. In economic analysis, understanding how indicators like GDP, inflation, and unemployment interact is crucial for building robust models and drawing meaningful conclusions. By visualizing multiple variables together, you can uncover hidden patterns, detect potential correlations, and identify outliers that may influence your interpretation of economic trends.

A pairplot in seaborn displays scatter plots for every pair of variables in your DataFrame, along with histograms or kernel density estimates on the diagonal. When you look at the pairplot above, you can quickly see the linearity or non-linearity between GDP and inflation, GDP and unemployment, and inflation and unemployment. For example, a downward trend in the scatter plot between GDP and unemployment may suggest that as GDP increases, unemployment tends to decrease. The diagonal plots help you examine the distribution of individual variables, which is useful for detecting skewness or outliers. By interpreting these plots together, you gain a holistic view of the interrelationships among your economic indicators.
