{"version":"1.0","type":"rich","title":"CSV to JSON","description":"This example demonstrates a hierarchical visualization of iNaturalist butterfly observation data, converting a CSV file into a nested JSON-like structure. The code loads the data using `d3.csv` and transforms each row into objects containing fields such as location coordinates, dates, and taxonomic classifications from kingdom down to species. The visualization displays this hierarchical taxonomic data using a tree layout, with nodes rendered as circles and connecting links as paths. The implementation relies on D3 v5’s selection and data-joining methods to bind the processed data to SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c4721ff41a464d05ae04c0c57bd48d9b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
