This bar chart visualizes sales figures for 100 products, with each bar’s height mapped to the product’s sales units. The visualization uses D3 v7 to load a CSV file from a GitHub gist, then renders an SVG with steel-blue bars that turn orange on hover. A band scale positions categorical products along the x-axis, while a linear scale maps sales values to the y-axis. The chart includes axis labels, a rotated x-axis to accommodate product names, and a title, with horizontal grid lines for readability.
