This scatter plot visualizes the relationship between student age at enrollment and first-semester grade, with points colored according to gender and retention status (retained versus dropped). Each dot encodes a single student record from the dataset, and hovering reveals precise age, grade, and gender values through a tooltip. The visualization uses D3 v7 with SVG rendering, employing `d3.scaleLinear` for the x and y axes, `d3.scaleOrdinal` for categorical coloring, and `d3.axisBottom` and `d3.axisLeft` for the coordinate system. A static HTML legend outside the SVG explains the four color-coded groups.
