{"version":"1.0","type":"rich","title":"TestActivity","description":"This interactive scatterplot animates through the Iris dataset, cycling the x-axis among four flower measurements (petal width, sepal width, petal length, and sepal length) every few seconds. The y-axis remains fixed on sepal length. Points are colored by species (setosa, versicolor, virginica) with a static legend, and axes update dynamically via D3's `scaleLinear`, `axisLeft`, and `axisBottom` APIs. The visualization uses D3 6.7.0 loaded via UNPKG, renders as an SVG with animated transitions driven by `setInterval`, and fetches CSV data from a GitHub gist.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/55008a7b2be646e29a821a9f5a9eebba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
