This example displays the top 10 countries most affected by COVID-19 as a 3D bar chart using the d3-x3d library, which bridges D3.js with X3D for WebGL rendering. The bars are generated from a CSV dataset containing case counts per country, loaded asynchronously via d3.csv. The chart uses d3.x3d.chart.barChartMultiSeries to create the three-dimensional visualization, with the axis and layout handled by the x3dom framework. The page includes custom CSS for styling the title and center alignment.
