This example visualizes the top 10 countries by COVID-19 case counts using a 3D stacked bar chart. Each column represents a country, with three stacked segments showing total cases, total recovered, and active cases. The chart uses the Highcharts library with its highcharts-3d module, enabling a rotated perspective via the `options3d` configuration (alpha, beta, and depth). Data is supplied directly in the series arrays, with categories labeled by country names on the x-axis and case numbers on the y-axis.
