{"version":"1.0","type":"rich","title":"loading_data_NH_2","description":"This example demonstrates asynchronous data loading with D3 v7, displaying the contents of a CSV file as formatted JSON text in a pre element. It uses `fetch()` to retrieve `data.csv`, `csvParse` from D3 to convert the raw CSV string into an array of objects, and then iterates through the parsed data to coerce the numeric columns (`sepal_length`, `sepal_width`, `petal_length`, `petal_width`) from strings to numbers. The visualization implements a unidirectional data flow where a `setState` function updates the application state, triggering a re-render that initially shows \"LOADING\" before the fetched data appears.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/36af61470b374379ad09a54f4df88e8d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
