{"version":"1.0","type":"rich","title":"tutorial3.2","description":"This scatter plot visualizes the Iris dataset, displaying sepal length against petal length, with species differentiated by filled symbols from a shape legend. The visualization uses D3 version 7 APIs including `scaleLinear`, `scaleOrdinal`, `symbolsFill`, and `axisLeft`/`axisBottom` for axes, while fetching the CSV data from GitHub. The code demonstrates the VizHub V3 runtime with a `main` entry point, interactive widgets for real-time updates, and the `state`/`setState` pattern for immutable state management.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1f076292b1274366af321269c49586a6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
