Radar Chart D3 V4
This example presents a redesigned radar chart (also known as a spider chart) built with D3 v4. It visualizes comparative values across six areas—Central, Kirkdale, Kensington, Everton, Picton, and Riverside—using a single data series rendered as a semi-transparent filled polygon. The chart features circular level lines with percentage labels, radial axes, and hover interactions that highlight the active polygon. The visualization is generated using SVG and includes smooth transitions on mouseover. The code is structured as a reusable `RadarChart.draw` function, allowing customization of dimensions, colors, and other options. It is based on earlier work by alangrafu and nbremer, and this version updates the chart to D3 v4.
