Fork of vendas_por_grupo_bar_chart
This horizontal bar chart visualizes product group sales quantities from a CSV file, ranking categories like footwear and accessories by units sold. The D3 v7 code uses `scaleLinear` and `scaleBand` to map data to SVG rectangles, with `axisBottom` and `axisLeft` generating labeled axes. Hover effects are applied via CSS, and the visualization is styled with a dark gradient background and bold yellow bars, with data loaded asynchronously via `csv()`.
