A 3D vertical bar chart compares total downloads for seven music artists across six app stores, with each store’s download counts stacked as distinct colored bars per artist. Built with Highcharts and the Highcharts 3D extension, it renders columns with depth, enabled via `options3d` (alpha, beta, viewDistance, depth), and uses `plotOptions.column` for stacking and grouping. The chart plots series arrays for each store, with categories on the x-axis, download totals on the y-axis, and a z-axis titled “Various Sources.” The example uses a grey background and a fixed-height container.
