This scatter plot visualizes a week of temperature data in San Francisco, displaying time on the x-axis and altitude on the y-axis with steelblue circles. The visualization uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisLeft`, and `axisBottom` to render the axes and plot points. Data originates from Data Canvas - Sense Your City and is loaded from a raw CSV file on GitHub. The chart includes labeled axes, a title, and gridlines, all rendered as SVG elements.
