This interactive visualization displays a histogram of numeric attributes from the Spotify top-10s dataset, with a second card showing a scatter plot. Users can select columns and dynamically adjust bin width by dragging on a button. The code uses `d3.histogram()` with `d3.scaleLinear` and `d3.axisBottom`/`d3.axisLeft` for rendering, while transitions animate axis updates and bar shapes. Hovering highlights bars and reveals count labels, with SVG output generated via D3 v4.
