{"version":"1.0","type":"rich","title":"activity6_tutorial3.2","description":"This interactive scatter plot visualizes the Iris dataset, displaying sepal length against petal length. Points are color-coded by species using a shape-based legend, with axes labeled accordingly. Built with D3 v7, the visualization dynamically loads CSV data from GitHub and uses `scaleLinear`, `scaleOrdinal`, `symbolsFill`, and `symbol` APIs for scaling and rendering. The code structure separates chart components into modular functions for axes, shape legends, and the main scatter plot, with a reactive state management pattern handling asynchronous data fetching and re-rendering on updates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3e7ba782bcde466db8aa23a53678a956?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
