This scatter plot shows temperature readings in San Francisco over a week, with time on the x-axis and temperature on the y-axis using a time scale and linear scale, respectively. The data is loaded from a CSV file and parsed into numeric and date formats. D3 v5 APIs such as `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` render the axes, while circles are drawn on an SVG canvas with semi-transparent styling. Grid lines are generated via tick sizes, and axis labels are added manually.
