This scatter plot visualizes hourly temperature readings in San Francisco over time, with time on the x-axis and temperature on the y-axis. Each orange circle represents a single measurement, revealing seasonal and daily temperature patterns. The visualization uses D3.js version 7 with SVG rendering, loading data from a CSV file via `d3.csv`. It employs `scaleTime` and `scaleLinear` for axes, `axisBottom` and `axisLeft` for ticks, and custom labels for clarity. Grid lines are generated using negative tick sizes, while the title and axis annotations are added as SVG text elements.
