{"version":"1.0","type":"rich","title":"Smoothed D3.js Radar Chart","description":"A smoothed D3.js radar chart compares five smartphones across four attributes—battery life, brand, contract cost, and design quality—using overlapping, semi-transparent polygons. The chart renders in SVG with animated, cardinal-closed paths that round the blob strokes, and includes a circular grid with percentage labels, a glow filter, and tooltips. Built with D3 v3 and React, it uses `d3.scale.ordinal` for colors, `d3.scale.linear` for radial scaling, and a custom `RadarChart` function adapted from Nadieh Bremer’s design.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea4bb94e00544c45b4b91682828b0a99?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
