A scatter plot visualizes the relationship between hours studied and exam scores across 150 students, using D3 v7 to load CSV data and render SVG circles mapped through linear scales. The chart includes labeled axes, a bold title, and semi-transparent steelblue points sized at 4 pixels. Data comes from a local `study_scores.csv` file, with axes and scales configured via `d3.scaleLinear`, `d3.extent`, and `axisBottom`/`axisLeft`.
