{"version":"1.0","type":"rich","title":"Fork of Loading Data practice","description":"This example demonstrates a unidirectional data flow pattern: a circle follows the mouse cursor while loading and displaying the Iris dataset. The visualization first fetches `data.csv` containing sepal and petal measurements, parses it with `csvParse`, and converts the numeric string values to numbers. A `pre` element displays the JSON-formatted state data, which transitions from a string `\"loading\"` to the complete dataset. The code uses D3 v7's `select` and `join` APIs to manage the DOM and implements explicit `setState`/`render` functions to maintain predictable one-way data flow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ca4af4af366145f4ba76bdea6fd185cd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
