This example shows a 3D scatter plot comparing two sets of data points across three variables: a1/s1/h1 and a2/s2/h2. The visualization uses two distinct marker styles—one with black outlines and one with pink circles and green outlines—to differentiate the datasets. The code loads CSV data from a GitHub gist using the D3.js `d3.csv` function, then constructs the plot with Plotly's `scatter3d` trace type. The layout removes all margins to maximize the plot area, and the chart is rendered into a div using `Plotly.newPlot`.
