This area chart visualizes Spotify listening habits, showing total songs played per week. The visualization combines a filled area with a line overlay and circular data points, using steelblue for the area and line with tomato-colored points. Tooltips provide exact values on hover. Built with D3 v7, the chart employs `scaleLinear`, `axisBottom`, `axisLeft`, `area()`, and `line()` with `curveMonotoneX` smoothing. Data comes from a Gist-hosted CSV file displayed in an SVG rendered at 900×520 pixels.
