This line chart visualizes a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis, using a smooth curved path to connect the data points. The chart is rendered as an SVG using D3 v6, with `d3.csv` loading the dataset and `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` constructing the axes. A `d3.line` generator with `curveBasis` creates the smoothed line, while dashed gridlines and labeled axis titles enhance readability. Data comes from a CSV file hosted on VizHub.
