{"version":"1.0","type":"rich","title":"fcc-d3-01","description":"A heatmap visualizes monthly global land-surface temperature variations from 1753 to 2015, with the base temperature displayed as a subtitle. Each cell represents a month-year pair, colored by year and opacity scaled by temperature deviation. The visualization uses d3.json to load data from a freeCodeCamp repository, d3.scaleOrdinal, d3.scaleLinear, and d3.scaleBand for scales. SVG rendering includes custom axes, ticks, and a hover tooltip that displays the exact year, month, and temperature values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d96b94ac60ef4eb292fb023c266a8dde?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
