This reusable D3.js scatter plot visualizes the relationship between math and physics scores for 40 students, with points colored by group membership. The chart uses `d3.csv` to load the dataset and custom scales via `d3.scaleLinear` for both axes and `d3.scaleOrdinal` for the categorical color encoding. The reusable function accepts parameters for data, axis value accessors, labels, dimensions, and title, rendering the chart as SVG with axes, labels, a legend, and semi-transparent circles. This design allows the same function to be applied to different datasets and attributes without modification.
