This line chart displays temperature readings over a week in San Francisco, with time on the x-axis and temperature on the y-axis. The visualization uses an SVG rendering approach with D3 v6, employing `scaleTime`, `scaleLinear`, and `line` with `curveBasis` to create a smooth curve. The data is loaded from a CSV file hosted on VizHub, and axes are generated using `axisLeft` and `axisBottom` with custom tick styling. Grid lines and labeled axes clarify the temporal trend in temperature.
