This line chart displays one week of temperature in San Francisco, with time on the x-axis and temperature in Celsius on the y-axis. The data is loaded from a CSV file over HTTP. Using D3 v5, the visualization employs `scaleTime` and `scaleLinear` for axes, with `axisBottom` and `axisLeft` to render tick marks. A `line` generator with `curveBasis` draws the smooth path, while SVG elements handle the chart title, axis labels, and gridlines. The minimal styling uses a teal background and colorful axis text.
