This example builds a reusable scatter plot comparing monthly Sales and Profit metrics from a CSV dataset. The chart displays eight data points as steelblue circles, with an x-axis for Sales and a y-axis for Profit, using a linear scale for both dimensions. The code leverages D3 v7’s `d3.csv` for data loading, `d3.scaleLinear` for scaling, and `d3.axisBottom`/`d3.axisLeft` for axes. A custom `scatterPlot` function encapsulates the chart logic, allowing flexible reuse with different data mappings and labels, rendered as an SVG.
