This 3D scatter plot visualizes student performance by plotting English, Science, and History scores against Age and Maths grades. Three distinct marker styles represent each subject, allowing comparison of academic metrics across age groups. The visualization uses Plotly’s `scatter3d` type via the `Plotly.newPlot` API, with data loaded from a CSV file using D3 version 3’s `d3.csv` function. The code defines three traces with customized marker colors, sizes, and opacity levels to differentiate the subjects.
