{"version":"1.0","type":"rich","title":"Smoothed D3.js Radar Chart","description":"Three fictional smartphone brands—iPhone, Samsung, and Nokia—are compared across eight attributes such as battery life, brand, and price using a smoothed radar chart. The chart renders as an SVG with animated, rounded strokes and semi-transparent filled areas, and includes a glow filter, circular grid, and percentage labels. Built with D3.js v3, it uses ordinal color scaling and a custom radar chart function that applies cardinal-closed interpolation for the smoothed lines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d8c48e7fff844f60a2c41ad531435181?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
