**Butterfly Chart** is a type of bar chart that spreads symmetrically, resembling butterfly wings. It’s particularly useful for comparing opposing values, such as Male vs. Female, Yes vs. No, or Online vs. Offline, using a common scale.

In this post, we’ll use South Korea’s **2025 population projection data** from Statistics Korea to create a **Population Pyramid** in Tableau.

### **Step-by-Step: Building a Population Pyramid**

1. Drag the **Age** field to Rows and place the **Male** and **Female** fields as bar charts on Columns.

1. To keep both bars symmetrical, create a calculated field that returns the maximum value between the two measures. Add this as a **reference line** on both sides, and hide the label, tooltip, and line.
