A bar chart displays total ad spend across management entities, sorted vertically with steelblue rectangles encoding values from a CSV dataset. The visualization uses D3 v5’s `csv` loader, `scaleLinear` for the x-axis, `scaleBand` for categorical y-axis positioning, and `axisLeft`/`axisBottom` for ticks. SVG rendering occurs via appended `rect` elements, with margins and transforms controlling layout.
