A radar chart visualizes the music genre preferences of five artists across five axes—hip hop/R&B, electronic/dance, Latin pop, pop, and rock—using the `RadarChart.chart()` API from the d3.v3 library. The SVG rendering animates with a randomized dataset generated by `randomDataset()`, which revalues each artist’s genre scores. Custom CSS classes—such as `.Joachim_Garraud` and `.Kobe`—assign distinct fill colors to each artist’s polygon, while the chart’s tooltip feature displays axis values on hover.
