📊 Understanding the Population Difference Chart

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

Left Side (Males)

Blue = Japan has more males

Green = Italy has more males

Right Side (Females)

Pink = Japan has more females

Orange = Italy 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 Italy has more males in that age group.
