📊 Understanding the Population Difference Chart
This visualization shows where and by how much the populations differ between China and United Kingdom for each age group, split by gender:
Left Side (Males)
Blue = China has more males
Green = United Kingdom has more males
Right Side (Females)
Pink = China has more females
Orange = United Kingdom 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 United Kingdom has more males in that age group.
