This example visualizes the relationship between time and temperature for a set of cars using an SVG line chart. The data is loaded from a CSV file using `d3.csv`, with timestamps parsed into `Date` objects and temperatures into numbers. The visualization employs `d3.scaleTime` and `d3.scaleLinear` for the axes, and draws a smooth curve using `d3.line` with `curveBasis`. The chart includes labeled axes, gridlines, and a title, with styling applied via CSS classes.
