{"version":"1.0","type":"rich","title":"Heat Map: Monthly Global Land-Surface Temperature","description":"This heat map visualizes monthly global land-surface temperatures from 1753 to 2015, with each cell colored according to temperature variance from a base of 8.66°C. The visualization uses D3 v5 with SVG rendering, employing `scaleTime` for the year and month axes, `scaleOrdinal` with a custom color range for temperature values, and `d3-tip` for interactive tooltips displaying month, temperature, and variance details. A color legend with discrete temperature bands appears beneath the chart. Data comes from the FreeCodeCamp ProjectReferenceData GitHub repository.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e3da07bb1b0b4255bcf82197b2d3f1fe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
