{"version":"1.0","type":"rich","title":"Activity8_Task4","description":"A bubble chart displays the Iris dataset, plotting sepal width on the x-axis against sepal length on the y-axis. Each circle's radius encodes petal length, while its color distinguishes the three species (setosa, versicolor, and virginica) using a custom ordinal scale. Built with d3.v7 and rendered as SVG, the visualization includes interactive tooltips on hover, a legend, and animated opacity transitions for a polished presentation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e74d8cb8c197497fa4ae098110daa777?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
