This example shows a three-dimensional grouped bar chart comparing download counts for seven popular apps across six different app stores, with each store represented by a distinct colored bar series. The chart uses Highcharts with the highcharts-3d.js module, configuring the chart’s 3D perspective through the `options3d` object, setting alpha, beta, and depth values. Bars are rendered with a specified depth and grouped along the z-axis using `groupZPadding`, while the x-axis lists app names and the y-axis tracks total downloads; stacking and grouping are enabled via the `plotOptions.column` settings. Data values are hardcoded in the series arrays, with each series named after its respective store.
