This bar chart displays the distribution of calories across different cereal brands, with each bar representing a specific cereal’s calorie count. The visualization uses D3.js v7 to load CSV data from a GitHub gist, parse the numeric calorie values, and render the chart as SVG. The code employs `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the continuous y-axis, with axes formatted via `d3.axisBottom` and `d3.axisLeft`. Cereal names on the x-axis are rotated for readability, while bar heights encode the calorie values directly. The chart’s layout and margins are defined programmatically, and error handling logs any data-loading issues.
