This scatter plot displays temperature readings over a week in San Francisco, with time on the x-axis and temperature on the y-axis. Each circle represents a single measurement, using d3.scaleTime and d3.scaleLinear to map the data. The chart includes labeled axes with gridlines and a title. Data is loaded as CSV from a VizHub dataset, parsed into Date and numeric values, and rendered as SVG circles using D3 v5 selection and enter/append methods, with custom margins and axis labels styled via CSS.
