This scatter plot visualizes the relationship between study hours and exam scores, with each point representing a student. The chart reveals a curved pattern where scores initially rise with study hours, peak around 48 hours, then decline, suggesting diminishing returns. Built with D3 v7, the visualization loads data from a CSV file and renders circles as SVG elements. The code uses `d3.csv` to parse the data, `d3.scaleLinear` for both axes, and `d3.axisBottom` and `d3.axisLeft` to generate the scales.
