This bar chart displays the average annual temperature for numerous U.S. cities, with each bar’s height corresponding to the temperature in degrees Celsius. Built with the D3.js library using `d3.scaleBand` and `d3.scaleLinear`, the visualization renders as SVG on a light background. It reads the `temperature_data.csv` file, parses the numeric temperature values, and draws the bars, axes, and a rotated x-axis label list using D3's modular APIs. The chart’s title and axis labels are added as SVG text elements.
