{"version":"1.0","type":"rich","title":"fcc-d3-03","description":"This example visualizes monthly global land-surface temperature anomalies from 1753 to 2015, using a heatmap of red rectangles over an SVG. It relies on React and D3 v7 (via `json`, `scaleLinear`, and `scaleBand`) to render axes, tooltips, and color opacity based on temperature variance. The data comes from the freeCodeCamp global-temperature JSON file. Hovering over a bar displays the year, month, actual temperature, and variance using a positioned tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d0fe3f02006b40c0aea2240357bdb397?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
