This example shows a radial bar chart plotting five data series as concentric circular rings, with each series represented by a wedge extending from the center to a value on a 0–100 scale. The visualization uses D3.js version 7.8.4 to generate an SVG, employing `d3.lineRadial` with `curveLinearClosed` to create the series paths, `d3.scaleLinear` for the radius mapping, and SVG circles as grid levels. Axis labels are positioned using trigonometric calculations based on the angle slice for each series.
