This scatter plot visualizes customer data from a CSV file, showing the relationship between annual income and spending score, with each dot colored by gender. The visualization uses D3.js v7 to render SVG circles, with a tooltip that appears on mouseover to display detailed customer information like age, purchase frequency, and satisfaction rating. The chart includes axis labels, a title, and a legend, with scales computed via `d3.scaleLinear` and `d3.extent` for data domains.
