This D3 bar graph visualizes monthly sales volumes for Victoria Sponge cakes, with months on the x-axis and volume sold on the y-axis. The chart uses sample data from Application Studio, rendered as FireBrick-colored bars within an SVG canvas. It leverages d3.scaleBand for categorical month positioning, d3.scaleLinear for the numeric axis, and d3.axisLeft and d3.axisBottom to draw the axes with labeled ticks.
