This example shows a smoothed radar chart for a single Nokia smartphone, displaying values across eight attributes such as Battery Life, Brand, and Contract Cost. The chart uses D3.js v3 with SVG rendering and animation, drawing circular grid levels, radiating axes, and a rounded, cardinal-closed path for the data area. It employs ordinal scales for color, linear scales for radius, and a glow filter, with the design initially written by Nadieh Bremer. The React starter code wraps the D3 visualization, and the data is hardcoded as an array of axis-value pairs.
