This interactive visualization displays a stacked area chart of the user’s music plays across 52 weeks of 2018, broken down by artist and genre. The chart uses D3 v5 with SVG and animated transitions, letting viewers click a color legend to highlight a specific artist’s play counts. Data comes from Last.fm and is processed via `d3.csv` and `d3.hierarchy` into weekly aggregates. The rendering uses `d3.stack`, `d3.area`, and `d3.scaleLinear` with a `colorLegend` module for filtering.
