This scatter plot visualizes temperature readings in San Francisco over a week, using a blue line to connect the data points. The data is loaded from a CSV file and rendered as an SVG. The visualization uses D3 v5 APIs such as `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with a `curveBasis` to create a smooth path. Axes are labeled "Time" and "Temperature," and the chart includes grid lines and a title.
