This line chart displays temperature readings over a week, with circular marks positioned by timestamp and temperature values. The visualization uses React to render SVG elements, with D3 v5 utilities such as `scaleLinear` for axes, `extent` for domain calculation, and `timeFormat` for tick labels. Data comes from a CSV file containing San Francisco weekly temperatures, and hoverable tooltips show the formatted date for each point. The chart includes labeled axes for time and temperature, with a clean, minimalist styling.
