This visualization displays a week of temperature readings in San Francisco, plotting temperature against time as a smooth curved line. The chart uses d3.scaleTime and d3.scaleLinear to map the data, with axes rendered via d3.axisLeft and d3.axisBottom. The line is generated with d3.line using a curveBasis interpolation, and the data is loaded from a CSV file using d3.csv. SVG is the rendering approach, with styled grid lines and axis labels.
