This example visualizes daily surface air temperature data, where each year is represented as a separate line plotted across the days of the year. The lines are colored using a plasma color scale based on the year, with 2024 highlighted in red and a thicker stroke for emphasis. Using D3's `scaleLinear`, `scaleSequential`, and `flatGroup` utilities, the code groups the dataset by year and draws multiple paths. The visualization relies on the `@curran/daily-surface-air-temperature` data package and incorporates responsive axes from the `@curran/responsive-axes` library.
