This interactive 3D scatter plot visualizes the Iris dataset, displaying sepal length, sepal width, and petal length along the three axes. The visualization is built with Plotly.js, using its `scatter3d` trace type to render markers with a green outline. Data is loaded asynchronously via D3's `d3.csv` function, which parses rows from a remote CSV file. Each axis is configured with custom titles and distinct background and grid colors, while the plot's layout margins are minimized to maximize the chart area within its container.
