This scatter plot visualizes the relationship between math and science marks, with each point colored by performance category: green for 'Excellent', orange for 'Average', and red for 'Needs Improvement'. Built using D3 v6, it uses a reusable chart function with setter methods for customization, d3.scaleLinear for axes, d3.scaleOrdinal for color mapping, and d3.symbolCircle for point shapes. SVG renders axes, labels, a title, and a legend showing the categories.
