{"version":"1.0","type":"rich","title":"D3 Course Code Along - Blank Canvas","description":"This visualization displays world population changes from 1000 to 2020 using a blank SVG canvas. The code imports geographic projection functions and topojson features, though the final rendering remains incomplete. It uses d3-geo projections including geoMercator and geoOrthographic, alongside d3-selection and d3-zoom, with population data loaded from a CSV file. The map paths are styled with hover effects, but no actual geographic or data-driven shapes are drawn in the current implementation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/daf5f13e16e44667809f45d77f5f1b98?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
