This example shows a smoothed radar chart comparing multiple entities across several dimensions, with data for hospitals and products rendered as overlapping, semi-transparent polygons. The visualization uses D3.js version 3.5.6 to generate an SVG with circular grid lines, radiating axes, and animated blobs, with a glow filter added for visual emphasis. It relies on D3 scales for ordinal colors and linear radius mapping, with options for rounded strokes, tooltips, and level labels. The chart is built for React integration and uses static, embedded data arrays.
