A bar chart displays happiness scores for ten countries, with horizontal bars sorted from Finland’s highest score to Austria’s lowest. The visualization loads data from a CSV file and renders SVG rectangles using D3 v5’s `scaleLinear` for bar widths, `scaleBand` for vertical positioning, and `selectAll`–`data`–`enter` joins. The chart fills the entire 960×500 SVG canvas, with no axes or labels, emphasizing raw score comparisons across countries.
