A bar chart displays the daily earnings of named individuals, with purple bars scaled along linear and band axes. The chart loads CSV data from a GitHub gist, parses the numeric `amounts` field, and uses `d3.scaleBand` and `d3.scaleLinear` to map categories and values. The SVG rendering appends rectangles via `d3.selectAll` and adds axes with `d3.axisBottom` and `d3.axisLeft`.
