This example shows a scatter plot of one week of temperature data from a CSV file hosted in a GitHub gist, with time on the x-axis and temperature in degrees on the y-axis. The visualization uses React components to render SVG circles, with d3.scaleTime and d3.scaleLinear for scales, d3.timeFormat for weekday tick labels, and d3.extent for domain calculation. Axes are custom-built using React, and each data point includes a title for hover-based tooltips. Data loading is handled asynchronously via d3.csv within a custom useEffect hook.
