This bar chart shows the relative wealth of billionaires across 18 industries, sorted from highest to lowest total worth. The visualization uses hardcoded data displayed as brown horizontal bars with value labels at the end of each bar. The code leverages D3 v7's `scaleLinear` for the x-axis, `scaleBand` for the categorical y-axis, and `axisTop` with grid lines to create a clean, annotated comparison of industry wealth.
