Fork of Smoothed D3.js Radar Chart
This example shows a radar chart comparing nutritional values across sixteen categories, including protein, fat, carbohydrates, calcium, and vitamins, for a single food item. The chart renders as a circular grid with five concentric levels, using SVG paths and smoothed, rounded strokes to create a distinct blob shape. It is built with D3.js version 3, leveraging the library’s linear scale for radial positioning, ordinal color scaling, and SVG filters for a glow effect. The visualization includes interactive hover tooltips and animated transitions, with data displayed as percentage values.
