This bar chart compares Total Ad Spend across Management Entities, with the y-axis inverted so taller bars represent lower spending. The visualization uses D3 v5’s `scaleBand` and `scaleLinear` for positioning, along with `axisLeft` and `axisBottom` for axes. Data is loaded from a CSV file and rendered as SVG rectangles with a steelblue fill. The chart includes test entries beyond the primary delivery-platform data, and the code applies a monospace font style to all text.
