A line chart displays Denton temperature readings from December 21 to December 30, 2022, with dates on the x-axis and temperatures on the y-axis. Built with d3.v5, the visualization uses `scaleTime` and `scaleLinear` to map data, `axisBottom` and `axisLeft` for labeled ticks, and a `line` generator with `curveBasis` for the smoothed red path. The CSV data is loaded from a GitHub gist and rendered as SVG, with axis labels and a title.
