A horizontal bar chart ranks Nigeria's ten largest states by land area, with Niger, Borno, and Taraba likely among the top. The visualization uses React to render SVG elements, with scales and data loading handled by d3.scaleBand and d3.scaleLinear. The code imports the d3.csv parser to fetch data from a GitHub Gist, and formats axis tick labels using d3.format. Bars are drawn as rect elements, with tooltips provided by SVG title elements.
