This line chart visualizes one week of temperature measurements in San Francisco, using time on the x-axis and temperature on the y-axis. The chart is rendered as an SVG using D3 v6, with scales from `d3.scaleTime` and `d3.scaleLinear`. The line path is generated with `d3.line` and a `curveBasis` smoothing curve. Axis labels and grid lines are added via `d3.axisBottom` and `d3.axisLeft`, and data is loaded from a CSV using `d3.csv`. The visualization highlights temperature trends over the week with a maroon line against a clean, grid-lined background.
