{"version":"1.0","type":"rich","title":"Heat Map: Monthly Global Land-Surface Temperature","description":"This heat map visualizes monthly global land-surface temperature anomalies from 1753 to 2015, with a base temperature of 8.66°C. Each cell represents a month and year, colored by temperature variance using a custom 14-color scale. The visualization is built with D3 v5, using `scaleTime` for axes, `scaleLinear` for color mapping, and SVG rectangles for rendering. Data is fetched from the FreeCodeCamp ProjectReferenceData JSON source, while the legend and axis labels are generated with `axisBottom` and `axisLeft`. The code includes commented-out tooltip logic, but no interactive tooltips are active in the final render.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ddf0412b35f14cd99e0524a34082c0ad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
