This example visualizes a week of temperature readings in San Francisco as a scatter plot, with time on the x-axis and temperature on the y-axis. Each circle represents a single measurement, and hovering reveals the exact timestamp. Built with React and D3 v5, the visualization uses `scaleTime` and `scaleLinear` to map data to SVG coordinates, while custom `AxisBottom` and `AxisLeft` components render the ticks. The code loads data from a CSV file containing the "Data Canvas Sense Your City" dataset and formats the time axis using `timeFormat("%a")` for day abbreviations.
