This example shows a 3D stem plot with 100 points arranged in a circular spiral, where each point is connected to the base by a vertical stem. Using d3.v6 in an SVG renderer, the code constructs the visualization by applying rotation transformations to a group and drawing lines with x, y, and z coordinates. Axes and labels are manually added for the x, y, and z dimensions, styled in black with steelblue stems on a pink background.
