This interactive visualization uses stacked area charts to show how the composition of national diets—by commodity categories like cereals, pulses, meat, and dairy—changed annually from 1961 to 2013 for a selection of countries. The data comes from the FAO (2017) food supply dataset, with each stream colored via d3-color and rendered as animated SVG. As years advance, the proportional height of each category shifts, revealing long-term dietary transitions such as increasing meat consumption or declining reliance on cereals. The chart animates through time, allowing comparisons across countries and categories in kilocalories per person per day.
