This radar chart compares three smartphone brands—Apple, Samsung, and Nokia—across eight consumer preference axes such as Battery Life, Brand, and Price of Device. A dark-themed SVG rendering uses d3.lineRadial with curveLinearClosed to draw five concentric level lines, while d3.scaleOrdinal assigns distinct colors to each brand’s filled polygon. Axis lines and labels are generated from the dataset, with animated opacity and dot markers highlighting each brand’s value profile.
