This scatter plot visualizes the relationship between students’ math and science marks, with each green circle representing a student’s scores on the two axes. The data is loaded from a CSV file via `d3.csv`, and the plot is rendered in SVG using `d3.select`, `d3.scaleLinear`, `d3.extent`, and the `axisLeft` and `axisBottom` components from D3 v6. The chart includes labeled axes, a title, and uses a simple point-radius of 6 pixels. The visualization sizes itself to the full browser window.
