This line chart visualizes one week of temperature data in San Francisco, with time on the x-axis and degrees Celsius on the y-axis. The line uses a smooth basis curve to connect daily temperature readings. Built with d3.v5, the code employs scaleTime, scaleLinear, axisBottom, axisLeft, and line with curveBasis to render the SVG. Data is loaded from a CSV file containing timestamp and temperature values, with the chart styled using maroon strokes and labeled axes.
