This area chart displays hourly temperature readings in degrees Fahrenheit for San Francisco over one week in May 2020. The visualization uses D3.js v5 to render an SVG path with a smoothed curve, mapping timestamps to a time scale on the x-axis and temperatures to a linear scale on the y-axis. The chart includes axis labels, grid lines, and a title, with the data sourced from a CSV file obtained from meteoblue’s weather archive. The area fill and styling are defined via CSS classes.
