This scatter plot visualizes the relationship between a customer's annual income and their spending score, with each circle representing an individual customer. The graphic uses a green fill with partial opacity for the points, making overlapping data visible. The visualization is built with D3.js, using the `d3.scaleLinear` function to map data values to x and y coordinates, and `d3.axisBottom` and `d3.axisLeft` to render the labeled axes. The data is a small embedded JavaScript array containing customer attributes like age, income, and spending score.
