This bar chart displays the top 10 companies by bicycle sales, rendered as horizontal bars within an SVG. The visualization is built using React and D3, with data loaded from a CSV file. The code uses `d3.csv` to fetch and parse the data, and `d3.scaleBand` and `d3.scaleLinear` to map company names and sales values to visual positions. Each bar’s width is proportional to its sales figure, with gridlines and axis ticks generated from the linear scale.
