This smoothed radar chart compares the attributes of three smartphone brands—iPhone, Samsung, and Nokia—across eight dimensions such as battery life, brand, and price. Each brand is represented as a colored, closed polygon, with axes radiating from the center and concentric grid circles indicating value levels. The visualization uses D3.js version 3 to render SVG elements, including paths for the data blobs, circles for the grid, and text labels, with an applied glow filter for visual enhancement. Numerical values are displayed as percentages, and the chart is drawn using the `RadarChart` function originally designed by Nadieh Bremer.
