This 3D scatter plot visualizes three axes labeled A, Z, and Y, with points rendered in an interactive plotly chart. The example demonstrates how to embed a Plotly visualization using the `plotly-2.9.0.min.js` CDN library alongside an older D3 version 3.5.17. While the HTML structure creates the chart container, the accompanying JavaScript file imports `select` from D3 version 7 to output text, showing a mixed-version workflow. The visualization itself relies on Plotly’s 3D rendering capabilities rather than custom D3 drawing.
