This chart shows daily coffee sales quantities as a vertical bar chart, with dates on the x-axis and sales quantity on the y-axis. The code loads CSV data via `d3.csv`, parses the Quantity field into numbers, and renders bars using `d3.scaleBand` and `d3.scaleLinear`. It appends SVG rectangles, styled with a steelblue fill, and adds axes using `d3.axisBottom` and `d3.axisLeft`. The x-axis labels are rotated for readability. The visualization relies on D3 v7 and renders entirely in SVG.
