This bar chart displays the number of Deezer fans for each album by the band Metallica, retrieved from the Wasabi API. Users can click the Ascending and Descending buttons to re-sort the bars by fan count or release date. The visualization uses D3 v4 with SVG and animated transitions, featuring a tooltip that shows album titles and fan numbers on hover. Data loads asynchronously via `fetch` and is processed with `scaleBand` and `scaleLinear` axes.
