This visualization plots one week of temperature readings in San Francisco as a scatterplot, with time on the x-axis and temperature on the y-axis. The data, loaded from a CSV file, is rendered as semi-transparent orange circles. The code uses D3 v6 functions including `scaleTime`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to construct the chart, with axis labels and a title added via SVG text elements.
