This scatter plot visualizes student grades, with English on the x-axis, physics on the y-axis, and points colored by class category (First, Second, or other). It uses D3 v6’s `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load and scale the data from a GitHub-hosted CSV and render axes. The plot is drawn as SVG circles with fixed radius, while additional science and math values are stored per mark but not visually encoded.
