This scatter plot visualizes a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis, using circular marks to represent each data point. The chart is built with D3 v6, leveraging `csv` to load data, `scaleTime` and `scaleLinear` for axes, and `axisBottom` and `axisLeft` for tick rendering. The SVG rendering includes axis labels, a title, and styled circles, with the data sourced from a CSV file hosted on VizHub.
