This 3D Scatter Plot visualizes the Iris dataset, plotting sepal length, sepal width, and petal length in one trace, and sepal length, sepal width, and petal width in another, using Plotly's `scatter3d` trace type. The markers are styled with size, opacity, and line properties, and rendered inside a `myDiv` container. The code loads data via `d3.csv` from a GitHub gist and creates the plot with `Plotly.newPlot`, using the Plotly CDN and D3 v3. The layout margins are set to zero for a full-bleed view.
