This example visualizes the Iris dataset as an interactive 3D scatter plot using Highcharts’ scatter3d chart type, with petal length, sepal length, and petal width mapped to the x, y, and z axes. Users can drag the plot to rotate the 3D view, implemented via custom mouse and touch event handlers that update the chart’s alpha and beta angles. The data is loaded from a remote CSV using D3’s `d3.csv` function and then passed into the Highcharts chart configuration, which also includes radial gradient point styling and a yellow page heading.
