This example displays a 3D scatter plot of iris flower measurements, with points colored pink and green representing different dimensions of calyx and corolla features. The visualization uses the Plotly JavaScript library to render the chart, while D3.js handles loading the dataset from a remote CSV file via the `d3.csv` function. The code overlays two scatter traces, one configured as `scatter2d` and another as `scatter3d`, within a single plot area, though only the 3D trace is visible in the rendering.
