This scatter plot visualizes one week of temperature readings in San Francisco, with time on the x-axis and degrees Celsius on the y-axis. The data is loaded from a CSV file hosted on VizHub. Using D3 v5, the code employs `scaleTime`, `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` to render axes with gridlines, while circles represent individual temperature measurements. The visualization is rendered as SVG, with a title, axis labels, and a semi-transparent steelblue fill for the data points.
