This scatter plot visualizes the relationship between math and reading scores for individual students, with each point's color indicating whether the writing score exceeds 70. Built with D3 v7, the SVG chart uses `d3.scaleLinear` for both axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.csv` with `d3.autoType` to parse the student performance data. Points are rendered as circles with a fixed radius and 70% fill opacity.
