This 3D scatter plot visualizes the calcium, vitamin, and protein content of vegetables as three-dimensional points. Each blue marker represents a vegetable, positioned according to its nutrient values from a CSV file loaded via `d3.csv`. The code uses Plotly’s `Plotly.newPlot` with a `scatter3d` trace, while `d3.csv` handles data parsing with the `unpack` function to extract columns. The layout defines styled axis titles for the three nutrient dimensions.
