This example shows a three-dimensional pie chart with extruded height, where each slice represents a numeric value from a hardcoded array. The chart is rendered as an SVG element using the `vizjs.org` library’s `viz.pie3d()` method, which takes the data array and a `height` parameter to create the 3D effect. The D3.js v4 library is used to select the SVG group element and apply the visualization via the `d3.select("g").call(pie3d)` pattern, using projection and geometric transformations to simulate depth.
