A 3D scatter plot visualizes nutrient data for various vegetables, mapping calcium, vitamin, and protein content along the three axes. The chart uses blue circular markers with green outlines and an opacity setting, rendered within a styled layout that includes axis titles and no margin. It loads a CSV dataset from a GitHub gist using D3's `d3.csv` function, then constructs the plot with Plotly's JavaScript API, specifically the `Plotly.newPlot` method and `scatter3d` trace type.
