A scatter plot displays temperature readings from a week of San Francisco weather data, with time on the x-axis and temperature on the y-axis. The visualization uses React to render SVG circles, with d3.scaleTime and d3.scaleLinear handling the scales. d3.axisBottom and d3.axisLeft are replaced by custom React components for tick marks, while d3.csv loads the dataset and d3.timeFormat formats the day labels. The chart highlights the daily temperature variation across the week.
