{"version":"1.0","type":"rich","title":"Nice barchart","description":"This example visualizes the distribution of object types across continents using a nested dataset from a SPARQL endpoint. Animated SVG bars represent counts of cultural heritage objects, with each group color-coded by geographical origin. The code fetches JSON data via `d3.json`, processes it through a chain of `.then()` transformations, and uses `d3.nest()` to structure the data by continent. Rendering relies on D3 v5’s SVG selection and animation methods, with styling defined in a linked stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b7c8c3fbbee04225a01f77cad370ff15?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
