This visualization displays daily temperature measurements in San Francisco as a smooth line chart over time, with individual data points marked as circles. The temperature values are plotted on the y-axis, while the x-axis maps timestamps using d3.scaleTime, and d3.scaleLinear handles the temperature scale. The line is generated with d3.line and curveBasis, and axes are rendered with d3.axisLeft and d3.axisBottom. Data is loaded asynchronously from a CSV file using d3.csv, and the SVG output includes a title and labeled axes.
