📊 Understanding the Population Difference Chart

This visualization shows where and by how much the populations differ between China and Saudi Arabia for each age group, split by gender:

Left Side (Males)

Blue = China has more males

Green = Saudi Arabia has more males

Right Side (Females)

Pink = China has more females

Orange = Saudi Arabia has more females

💡 How to Read: Each age group shows up to 2 bars - one on the left (male difference) and one on the right (female difference). The bar's color tells you which country has more people, and the bar's length shows by how much. For example, if you see a green bar on the left, it means Saudi Arabia has more males in that age group.
