This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City, with time on the x-axis and temperature in degrees Celsius on the y-axis. The D3.js v5 code uses `scaleTime` and `scaleLinear` for axes, `line` with `curveBasis` for the smoothed path, and `axisBottom` and `axisLeft` for gridlines and ticks. Data is parsed from a CSV file, rendered as an SVG, and styled with maroon strokes and custom fonts. The chart includes a title and axis labels, presenting a clean, minimal aesthetic.
