This example shows a 3D scatter plot of pool dimensions, plotting pool length, width, and height as three-dimensional coordinates. Each point is rendered as a blue marker with partial opacity, allowing for visual inspection of the relationships between the three measured variables. The visualization is built using Plotly's `newPlot` function, which receives data prepared from a CSV file loaded with d3.csv. The code constructs a single trace with multiple markers and uses a minimal layout with zero margins to display the plot.
