This scatter plot displays temperature readings in San Francisco over time, with each circle representing a data point and steelblue fill. The x-axis is labeled "Time," and the y-axis is labeled "Temperature." The visualization is built with D3 v5, using `scaleTime` for the time-based x-axis, `scaleLinear` for the y-axis, and `axisBottom`/`axisLeft` for grid lines and tick marks. Data is loaded from a CSV file hosted on vizhub.com, parsed into date and numeric temperature values, and rendered as SVG circles.
