This line chart displays one week of temperature data in San Francisco, with time on the x-axis and temperature on the y-axis. The visualization uses D3 v5 to load a CSV from VizHub, scale the data with `scaleTime` and `scaleLinear`, and render smooth curves via `line` with `curveBasis`. Axes are drawn using `axisBottom` and `axisLeft`, with custom tick styling, and the chart includes labeled axes and a title, all output as SVG.
