This 3D scatter plot visualizes the classic Iris dataset, showing sepal length, sepal width, and petal length as points in three-dimensional space. Each point uses a marker size of 12 with partial opacity, and the axes include distinct background colors and gridlines. The visualization is built using Plotly’s `scatter3d` trace type, with data loaded via D3’s CSV parser and rendered through WebGL. The code defines a custom color scale but does not color-code points by species, instead presenting all measurements in a single trace.
