This 3D scatter plot visualizes the iris dataset, showing sepal length, sepal width, and petal length as black markers with subtle gray outlines. Built with Plotly.js and D3.js, the code loads CSV data via d3.csv, unpacks columns into x, y, and z coordinates, and renders an interactive WebGL scatter plot. The scene includes labeled axes for the first two variables and a generic "Z AXIS TITLE" placeholder, with markers sized at 12 and 0.9 opacity.
