A scatter plot of temperature over time, this React visualization uses D3.js scales and axes to map the data. The code defines axes and marks as separate React components, and uses `d3.scaleTime` and `d3.scaleLinear` to position circles. The `csv` function loads the Sense Your City dataset, and the `timeFormat` API formats x-axis tick labels. The chart is rendered as an SVG, with each data point displayed as a circle whose hover tooltip shows the timestamp.
