{"version":"1.0","type":"rich","title":"Earth Surface Temperature HeatMap","description":"This heatmap visualizes Earth’s surface temperature variations from 1753 to 2015, with each cell representing a month’s temperature relative to a base value. The color scale uses a custom ordinal scheme ranging from dark red (warm) to dark blue (cool), while hovering over a cell displays a tooltip with the exact month, temperature, and variance. The visualization is built with D3 v5, using `d3.scaleTime` for axes, `d3.scaleOrdinal` for colors, and `d3-tip` for interactive tooltips. Data comes from a JSON file containing `baseTemperature` and `monthlyVariance` values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0cb0b055d542490f856a7642f5dbce74?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
