A 3D bar chart visualizes sales for seven car manufacturers from 2015 to 2022. Each column is a manufacturer, with eight stacked segments per column representing annual sales; the chart’s depth axis maps years. The visualization uses the Highcharts library and its highcharts-3d JavaScript API, with options3d enabling perspective rotation (alpha 25, beta 40) and a set view distance. Data is hardcoded in the series arrays, with pink, yellow, and default color-coded segments for different years.
