This interactive scatter plot visualizes Spotify listening habits, mapping metrics like average listening time, total songs played, and mood score. Users switch X and Y axes via dropdown selectors, while circle color encodes Mood_Score through d3.interpolateTurbo, and size encodes New_Artists_Discovered via d3.scaleSqrt. Hovering reveals a tooltip and focus ring. The D3 v7 SVG chart includes gridlines, axes, transitions on points, and a custom CSV loader that flattens single-line data.
