A smooth, natural line chart depicts temperature readings over a week, with time on the x-axis and temperature on the y-axis. The visualization uses React components to render SVG graphics, leveraging D3 v7 functions like `scaleTime`, `scaleLinear`, `extent`, and `timeFormat` for data scaling and axis ticks. The natural curve, created with D3’s `line().curve(curveNatural)`, connects data points from a CSV source, while custom `AxisBottom` and `AxisLeft` components structure the chart with labeled ticks.
