This visualization shows the relationship between students’ math scores and their average reading scores, using an area chart with a smooth monotone curve. The chart plots math scores on the x-axis and average reading scores on the y-axis, with a semi-transparent teal area beneath a line to emphasize the trend. The code loads a CSV dataset via `d3.csv`, processes it with `d3.rollups` to compute mean reading scores per math score, and renders the result using `d3.area` and `d3.line`. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, all displayed in an SVG container.
