{"version":"1.0","type":"rich","title":"projection ","description":"This geographic map of Canada displays temperature distribution based on latitude, using a blue-to-red color gradient to represent colder northern and warmer southern regions. The visualization loads GeoJSON data from a GitHub repository and renders the country’s provinces using D3.js v7 with the `d3.geoMercator` projection and `d3.geoPath` for shapes. Province colors are computed from centroid latitudes via a simulated temperature model, with a legend gradient showing the cold-to-warm scale. The implementation utilizes `d3.scaleSequential`, `d3.interpolateRdYlBu`, and SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ce80972746d64a11af2730db66c11fd9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
