This example displays a scatter plot of annual gold prices, charting Date on the x-axis against USD on the y-axis. It uses d3.csv to load the data and d3.scaleLinear, d3.extent, d3.axisLeft, and d3.axisBottom to render the axes. The SVG circles are appended using a data join with attributes for position and fill. The chart is styled with a custom background color and large tick labels via CSS.
