This example visualizes the top 10 countries by sales as a horizontal bar chart, using a green-to-orange linear gradient to fill each bar. The chart is built with React and rendered as SVG, using D3 v6 scales (`scaleBand` and `scaleLinear`) to map country names and sales values to pixel positions. Data is loaded from a remote CSV file, and axis ticks are generated with `xScale.ticks()`, with both axis labels and bar values styled via CSS.
