This 3D bar chart visualizes the top 10 countries most affected by a virus, comparing case counts through extruded rectangular bars. The visualization uses the d3-x3d library to render three-dimensional graphics in the browser via X3DOM, while D3 v5 handles data loading and parsing from a CSV file. The chart displays each country on the x-axis with bar height representing the number of cases, styled with a pink heading and light blue background from the accompanying CSS.
