{"version":"1.0","type":"rich","title":"Monthly Global Land Surface Temperatures","description":"This visualization displays monthly global land surface temperatures from 1753 to 2015, with each cell’s color representing variance from the 1951–1980 average. A hover tooltip reveals the exact month, year, and temperature anomaly. The SVG chart uses d3.scaleTime for the x-axis, d3.scaleQuantize for color mapping, and d3.json to load the FreeCodeCamp dataset. Animated transitions appear only in the tooltip’s opacity changes, while a gradient legend is built with d3.scaleLinear and linearGradient stops.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ae5b62e10da44f980fa626eef6897d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
