A scatter plot shows a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis. Each circle represents a temperature observation, colored steelblue. The visualization uses D3 v5 to load CSV data, create scales with `scaleTime` and `scaleLinear`, and render axes with `axisBottom` and `axisLeft`. The SVG rendering approach draws circles directly, with dimensions set from the viewport. The data comes from a CSV file hosted on VizHub, with timestamps parsed as dates and temperatures as numbers.
