This 3D scatter plot visualizes COVID-19 data across countries, showing two traces: one plotting cured cases against dead cases, and another plotting active cases against dead cases. The visualization uses Plotly’s `scatter3d` type within `Plotly.newPlot`, with D3.js handling CSV data loading via `d3.csv` and the `unpack` function to extract columns. Data originates from a GitHub-hosted CSV file containing per-country case counts, rendered as colored markers with configurable opacity and line styling in a minimal HTML page.
