This interactive parallel coordinates chart visualizes audio features of songs by selected artists, including energy, liveness, valence, speechiness, and danceability. Users click buttons to load CSV data for different artists, which triggers a D3 v6 animation that redraws the plot lines. The SVG rendering uses d3.scaleLinear for axes, d3.scalePoint for positioning, and d3.scaleOrdinal to color lines by playlist genre, with a legend displayed on the right. The data is sourced from GitHub-hosted CSV files.
