{"version":"1.0","type":"rich","title":"Fork of Svelte + D3: Radial","description":"A radial line chart visualizes daily surface temperatures from 1940 to 2024, with each year represented as a single closed ring. The visualization highlights 2023 and 2024 in distinct pink and blue strokes while older years appear as faint white loops, emphasizing recent climate trends. Using d3’s `lineRadial` generator with a Catmull-Rom curve, the code maps day-of-year to angles and temperature values to radii via `scaleLinear`. Yearly groups are separated with d3.groups, and opacity is scaled by year to show historical density. The SVG renders responsively, with data sourced from climatereanalyzer.org.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1dfea1f9221e49f6b159e03c15034c91?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
