This interactive 3D scatter chart visualizes the Iris dataset, plotting petal length, sepal length, and petal width as points in three-dimensional space. The chart uses the Highcharts library with its highcharts-3d module to render the scatter3d series, while D3.js (d3.csv) loads the data from a remote CSV file. Users can rotate the plot by dragging with mouse or touch events, which updates the chart’s alpha and beta angles via Highcharts’ chart.update method. The visualization also applies radial gradient colors to the points and frames the plot with semi-transparent grid planes.
