This line chart displays a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to draw a smooth green path. Data is loaded from a CSV file via `d3.csv`, with timestamps parsed as `Date` objects and temperatures as numbers. The SVG renderer includes styled axis labels, grid lines, and a title.
