This interactive bar plot displays the top ten tracks by popularity within a selected music genre, using data loaded from a CSV file. A dropdown menu lets users switch between genres, triggering a smooth transition animation as bars update to reflect the new ranking. The visualization is built with D3.js v7, using `scaleBand` and `scaleLinear` for axes, `transition().duration()` for animated updates, and SVG rendering with rotated axis labels for track names.
