This example creates a static bar chart visualizing food-related data from an external CSV file. It uses D3 v7 scales and axes—`d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`—to map years and values, with y-axis labels formatted as dollar amounts. The chart is drawn inside an SVG with a fixed margin, and the data is loaded asynchronously via `d3.csv`. Only the axes are rendered; no bars or other marks are added.
