This line chart visualizes one week of temperature data in San Francisco, using timestamps on the x-axis and temperature values on the y-axis. The chart renders an SVG with a smooth curved line, grid lines, axis labels, and a title, with all data drawn from a CSV sourced from Data Canvas. The code leverages D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, `line`, and `curveBasis`, and parses the CSV asynchronously before generating the visualization.
