This example displays a 3D scatter plot showing student scores in English, Science, and History plotted against age and maths achievement. The visualization uses three separate traces, with each subject represented by a distinct color: blue for Science, black for History, and grey for English. The interactive chart is rendered using the Plotly JavaScript library within an HTML interface, with data loaded from a GitHub-hosted CSV file through D3’s `d3.csv` function. Users can rotate and explore the three-dimensional space to examine relationships between the variables.
