A scatter plot shows the relationship between study hours per day and GPA for 30 students, with points shaped and colored by academic track (CS, Data, or AI). The code uses D3 v7’s `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.symbol` to render SVG paths with circles, triangles, and diamonds. Axes include grid lines, and a custom legend maps each track to its shape and color. Data is loaded via `d3.csv` from a remote gist.
