This scatter plot displays temperature readings in degrees Celsius from San Francisco over a week, with time on the x-axis and temperature on the y-axis. The visualization uses D3 v5 APIs including `select`, `csv`, `scaleTime`, `scaleLinear`, `axisLeft`, `axisBottom`, and `extent` to map the data to SVG circles. The chart is rendered as an SVG with axes featuring grid lines, tick labels, and custom axis titles, all styled via an external CSS file. Data is loaded from a CSV file provided by the Data Canvas - Sense your City initiative.
