This visualization shows the average reading score for students grouped by their parents' highest level of education, from some high school through master's degrees. The D3.v7 line chart uses d3.scalePoint and d3.scaleLinear for axes, with d3.mean aggregation to compute the averages. Interactive tooltips appear on hover for each data point. The chart renders as an SVG, sourced from the "StudentsPerformance 2.csv" file, highlighting the relationship between parental education and student performance in reading.
