This scatter plot displays the relationship between the price and sales volume of various items, with each data point represented as a circle. The visualization uses D3.js version 7 to fetch data from a remote CSV file via `d3.csv`, then renders the chart as an SVG using `d3.scaleLinear` for both axes. Interactive tooltips appear on mouseover, displaying the item name, price, and sales volume. The axes are labeled and the chart includes a title, with styling applied through a separate CSS file.
