The Beer Style Explorer pseudo-viz combines bar length and line marks to compare beer styles. Bars encode the number of reviews per style, while an overlaid red line uses y-position to show the average rating for each style. The visualization uses D3's `select` and `line` APIs, with `scaleBand` and `scaleLinear` for the axes, and `axisBottom`, `axisLeft`, and `axisRight` to render the chart. Both signals are presented on a shared categorical x-axis, with the line connecting the average ratings across styles.
