{"version":"1.0","type":"rich","title":"Activity6_task4_Question","description":"This example visualizes the classic Iris dataset as an interactive bubble chart, plotting sepal length against sepal width for three species. Circle size encodes petal length, while color distinguishes species using a custom ordinal scale. Built with D3.js v7, it loads data via `d3.csv`, uses `d3.scaleLinear` for axes and bubble sizing, and renders as an SVG with animations. Hovering over a bubble reveals a tooltip with species and measurement details, and a legend identifies the color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6206d1da89684fd9b314b72da82ea99b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
