{"version":"1.0","type":"rich","title":"Transforming Data","description":"This example shows the average sepal length for each iris species from a CSV dataset of flower measurements. It first loads the data with `fetch` and parses it using `d3.csvParse`, then groups and aggregates the values with `d3.flatRollup` and `d3.sum`. The resulting summary is rendered as formatted JSON text inside a `pre` element using D3's `select` and data joins. The visualization demonstrates D3 v7 loading via UNPKG and local ES6 module imports.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
