This example shows a 3D vertical bar chart comparing total downloads for seven popular applications across six different app stores. Each app is positioned along the x-axis, with stacked volume bars extending along the z-axis to represent the download totals from each store, while the y-axis indicates the download count. The visualization uses the Highcharts library with its highcharts-3d module, enabling a rotated, perspective view through the chart’s `options3d` settings for alpha, beta, and depth. The data is hardcoded in the series arrays, with each store as a separate stacked series.
