This bar chart compares average project costs across different brands, using horizontal bars whose widths correspond to dollar values. The example demonstrates a simple client-side rendering approach: JavaScript parses a hardcoded data object (with placeholder values like “Brand A: $123.45”) and dynamically creates styled `div` elements, each with a width set to twice the cost, appended to a container styled via CSS. The included `index.js` shows a separate, incomplete CSV-processing pipeline using `fs` and `csv-parser` to calculate averages, but that logic is not connected to the chart’s rendering.
