This example shows a 3D bar chart comparing mobile phone sales across eight brands and six retail channels, with each series stacked along the chart’s depth axis. The visualization uses the Highcharts library with its Highcharts 3D extension, enabling a perspective view through configurable alpha, beta, and depth settings. Categories on the x-axis list brand names, the y-axis measures total sales, and the z-axis labels the store type; data points are hardcoded arrays within the series definitions. The chart’s dark background and light-green title emphasize the rendered columns for each retailer’s sales figures.
