A scatter plot displays one week of San Francisco temperature readings over time, with each semi-transparent steelblue circle representing an hourly observation. The x-axis maps timestamps using a time scale, while the y-axis maps temperature values with a linear scale, both with grid lines and clear axis labels. The visualization is rendered as an SVG using D3 v5, employing `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to construct the chart. Data comes from the Data Canvas - Sense Your City dataset via a CSV loaded with `d3.csv`, and a title labels the graph.
