This line chart visualizes one week of temperature data in San Francisco, plotted against time. The chart uses SVG rendering and D3 v5, with a smooth curve generated by the `d3.line` and `curveBasis` functions. Axes are created using `axisLeft` and `axisBottom`, while scales are set via `scaleTime` and `scaleLinear`. The data is loaded from a CSV file using `d3.csv`, and the visualization includes labeled axes and a title.
