This 3D bar chart visualizes car manufacturer data from the first six months using the d3-3d, d3-x3d, and X3DOM libraries, rendered as an interactive WebGL scene within a browser. The visualization displays monthly sales figures for multiple manufacturers as three-dimensional bars on an XZ axis plane, with a blue domain line marking the origin. D3.js v5 handles the data binding and scene construction, while X3DOM renders the 3D geometry, including cylinders for the axes and tick lines, directly in HTML5.
