This 3D scatter plot visualizes a dataset of flower measurements using two marker styles to represent different attribute combinations. The visualization uses Plotly's `scatter3d` trace type, with one series plotting flower length against itself and another plotting length against width. Data is loaded via D3's CSV parser from a GitHub-hosted dataset, and the chart renders inside a designated HTML division using `Plotly.newPlot`. The interactive plot supports rotation and zooming for exploring the three-dimensional point distribution.
