This 3D scatter plot visualizes the Iris dataset, displaying three dimensions (Area, Perimeter, and Kernel Length) as one series, with a second series replacing Kernel Length with Kernel Width. The plot uses the Plotly JavaScript library via the `Plotly.newPlot` function to render interactive 3D markers in a web page. Data is loaded asynchronously using D3's `d3.csv` to fetch a remote CSV, and the marker styles (size, opacity, and colors) are configured per series. The layout margins are zeroed to maximize the chart area.
