This bar chart displays product sales figures from a CSV file, with each product’s sales value represented by a steelblue bar. The visualization uses D3.js to create an SVG, scaling the x-axis with `d3.scaleBand` and the y-axis with `d3.scaleLinear`. Axis labels are rotated, and a title is added, all rendered via the D3 SVG API. Data is loaded asynchronously from a GitHub gist using `d3.csv`.
