This example displays two sets of three-dimensional scatter points from the Plotly `3d-scatter.csv` dataset. It shows the distribution of data points in x, y, and z coordinates, comparing two distinct groups differentiated by marker style—one with translucent, bordered circles and another with solid gray circles. The code uses the Plotly JavaScript library, called via `Plotly.newPlot`, along with `d3.csv` to fetch and parse the data. The `unpack` function extracts each coordinate column for the traces. A zero-margin layout removes all surrounding space.
