This visualization displays GDP values by country as horizontal bars. Built with D3 v7, it loads CSV data from a GitHub repository using `d3.csv`, then maps country names to the x-axis and GDP values to the y-axis with linear and band scales. Bars change color on hover, and a tooltip shows the country name and GDP value. The SVG chart is rendered with rotated x-axis labels for readability, with axes styled via CSS classes.
