This animated choropleth map visualizes hypothetical country-level data across the years 2008–2013. Built with D3 v3 and rendered in SVG, the map uses a color scale to encode numeric values from a CSV dataset, with each country's fill transitioning as users step through time. The visualization includes a year selector and animated transitions, allowing viewers to observe changing patterns across countries over time. The map is accompanied by a tooltip displaying the country name and its value for the currently selected year.
