A population data visualization animation: each country's population is turned into marbles that tumble down, with 1 marble representing 1 million people. 8,144 marbles in total, based on real 2024 population data, with every crisp clink of a collision synced to the simulated impact. Ideal for data explainers, educational short-form videos, and fun social media content.
You are an expert web designer. Build a stunning, production-ready page with

Structure the layout with a sticky header, feature grid, social proof and a final
call to action. Keep typography tight, spacing consistent and motion subtle.
