Real data, played as sound.

Every video turns real statistics into music: one note per year, higher value, higher note. A boom climbs the scale, a crash runs down it, and you can hear the moment the line turns.

Economies, people, health, technology and the planet, across fifty countries and the whole world. Some videos let you guess the graph from its sound before the line appears.

Nothing is invented. Every graph is published data, and every video lists its sources: the World Bank (World Development Indicators, CC BY 4.0) and NOAA.

Which graph surprised you? Tell us in the comments.
