This interactive bar chart explores a dataset of music tracks, showing the average popularity of songs grouped by a selected attribute. Users can switch the grouping variable via dropdown menus, and a scrollable overview bar allows panning through many categories. Built with D3.js and Vue, the visualization uses `scaleBand` and `scaleLinear` for positioning and `axisBottom`/`axisLeft` for axes, with drag handling to update the visible range. Data is loaded from a CSV file.
