This scatter plot visualizes temperature readings in San Francisco over a week, with time on the x-axis and temperature on the y-axis. Each blue semi-transparent circle represents a data point, and the chart includes labeled axes and a title. The code uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to position elements, with data loaded from a CSV via `csv()`. SVG rendering is used, and gridlines are created by removing axis domain lines while retaining ticks.
