This line chart displays a week of temperature readings in San Francisco, using a smooth curve to show the trend over time. The visualization employs D3 v5’s `scaleTime` and `scaleLinear` to map timestamps and temperature values, with `line` and `curveBasis` generating the path. It uses SVG rendering with custom margins, axis labels, and a title, styled via CSS. The data is loaded from a CSV hosted on VizHub, and the chart includes interactive axes with tick marks and padding.
