This example shows a 3D scatter plot of the abbreviatus dataset, comparing calyx length, calyx width, and two corolla measurements. It uses Plotly’s `scatter3d` and `scatter2d` trace types to render points as markers with varying colors and opacity, loaded via `d3.csv` from a GitHub gist. The visualization is embedded in a React app using the Plotly.js CDN, with margins set to zero for a minimal layout.
