This interactive visualization recreates the classic Gapminder chart, plotting GDP per capita against life expectancy for countries over time from 1800 to 2014. Users can filter by continent via a custom dropdown menu and animate the progression through years with a play button. The code uses D3 v7 scales, axes, and transitions for the SVG rendering, with a tooltip displaying country details on hover. Data is loaded as JSON from an external GitHub source, and a custom dropdown module handles the continent selection.
