This radial chart shows daily temperature patterns over a year, with light-steelblue bands for the full min–max range, steelblue bands for the typical interquartile range, and a line tracing the daily average. Built with D3’s `scaleUtc`, `scaleRadial`, `lineRadial`, and `areaRadial`, it renders circular month labels and radial gridlines. The data comes from the JSON file, which records daily average, minimum, and maximum temperatures.
