This visualization shows how temperature in San Francisco varies over a week, with time plotted on the x-axis and temperature on the y-axis. The scatter plot uses a circle for each hourly measurement, with a hover tooltip displaying the day of the week. Built with React and D3 v5, it loads data from a CSV file, uses `scaleTime` and `scaleLinear` to map the data, and renders axes and marks as SVG elements.
