This example presents a 3D vertical bar chart comparing download numbers for seven popular applications across six different app stores. The chart uses the Highcharts library with its highcharts-3d module, setting chart type to 'column' and enabling 3D rendering through the `options3d` configuration with alpha and beta rotation angles. The data series are grouped and stacked along the z-axis, representing download sources like App Store, Playstore, and OneStore, while the x-axis lists app categories. The y-axis displays total downloads, and the z-axis is labeled "Various Sources."
