This visualization displays daily surface air temperature data as a line chart, with each year represented by a separate line colored according to a plasma color scale, and 2024 highlighted in red. The graphic uses d3.scaleLinear for X and Y axes, d3.flatGroup to organize data by year, and d3.line to generate paths. Axes are rendered using the @curran/responsive-axes library, and data is loaded from a CSV file via d3.csv with d3.autoType.
