This scatter plot displays student grades, plotting English scores on the x-axis against Physics on the y-axis, with each point colored by class category (First, Second, or other). The code loads CSV data via `d3.csv`, applies `d3.scaleLinear` for both axes, and renders circles using SVG. It also encodes additional dimensions through the `rx` and `ry` attributes, mapping Science and Math scores to each circle’s horizontal and vertical radii, while using `d3.axisLeft` and `d3.axisBottom` for labeled axes.
