This bar chart visualizes sales volumes for different coffee menu items, displaying each beverage name along the x-axis and its corresponding sales quantity on the y-axis. The visualization uses D3 v7’s `d3.csv` to load data from a GitHub gist, then applies `d3.scaleBand` and `d3.scaleLinear` to map categories and values. Bars are rendered as SVG rectangles with a steelblue fill, and axes include rotated labels using `d3.axisBottom` and `d3.axisLeft`.
