This example displays a 3D scatter plot with two sets of markers, each representing a distinct series of data points. It uses Plotly.js to render the visualization, with a D3 CSV loader fetching the dataset from a GitHub Gist. The code defines two traces—one with default styling and another with gray markers—and plots them across x, y, and z coordinates. The layout removes all margins, and the chart is embedded in a designated div element.
