This area chart visualizes one week of temperature readings in San Francisco, plotting temperature in degrees Celsius against time. The data is loaded from a CSV file and rendered as an SVG using D3 v5, with an area path filled in maroon to emphasize the temperature trend. The chart uses `scaleTime` and `scaleLinear` to map the axes, `axisLeft` and `axisBottom` for tick labels, and the `area` generator with a `curveBasis` smoothing function. Both axes include gridlines and descriptive labels for time and temperature.
