This visualization displays a week of temperature readings in San Francisco as a smooth line chart, with time on the x-axis and temperature on the y-axis. The chart uses d3.scaleTime and d3.scaleLinear to map data from a CSV file, rendered as SVG via a d3.line generator with curveBasis. Axis labels, tick marks, and a title are styled through CSS, while d3.axisBottom and d3.axisLeft provide the scales.
