This scatter plot visualizes one week of temperature readings in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. Each steelblue circle represents a temperature observation at a specific timestamp. Built with D3 v5, the visualization uses `scaleTime` and `scaleLinear` to map the data, `axisBottom` and `axisLeft` to render the axes, and SVG circles for the data points. The temperature dataset originates from the Data Canvas - Sense Your City project.
