This bar chart displays the total sales for the top 15 U.S. states, ranked by revenue. Using React and D3 v6, the visualization loads CSV data from a Gist URL, maps state names to the y-axis, and scales bar lengths linearly. The SVG rendering employs `scaleBand` for categorical spacing and `scaleLinear` for numeric axes, with axis ticks and gridlines drawn manually. The chart highlights comparative sales figures across states, with a simple, clean layout for quick regional analysis.
