This 3D scatter plot visualizes a cancer dataset, plotting radius, area, and cancer status as three dimensions. Two traces render the same data points with different marker styles, both using gray tones for the circles. The visualization is built with Plotly's `scatter3d` trace type, with data loaded via D3's `d3.csv` function from a GitHub-hosted CSV file. The Plotly `newPlot` function renders the chart inside an HTML div.
