This example visualizes a week of temperature readings from the Data Canvas Sense Your City dataset. It is a scatter plot with a smooth natural curve line connecting the points, where the x-axis represents time and the y-axis shows temperature in degrees. The visualization is rendered in SVG using React and D3 v5, leveraging `scaleTime` and `scaleLinear` for axes, and `line` with `curveNatural` for the path. Hovering over any circle reveals its exact timestamp via a tooltip.
