This bar chart displays the proportion of immigrants in seven European countries, ranked from Luxembourg at 45.9% down to Germany at 14.5%. The visualization uses d3.csv to load the data, then d3.scaleBand and d3.scaleLinear to map countries and values to SVG rectangles. Axes are generated with d3.axisBottom and d3.axisLeft, and a steelblue fill colors each bar against a computed inner height.
