Arrange in a 10x11 grid (110 icons = 330M). Group icons by generation in contiguous blocks. Use person-shaped icons (fontawesome style) instead of squares. Add a legend showing generation names and birth years. Include population counts. Title: 'US Population by Generation (2024)'. Subtitle: 'Each figure = 3 million people'."
