This bar chart displays total ad spend by management entity, with bars sorted by the dataset’s original row order and scaled from zero to the maximum spend. The chart uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render an SVG, reading data from a local CSV via `d3.csv`. Bars are drawn as `<rect>` elements with a steelblue fill, while axes and labels use the default D3 text styling.
