{"version":"1.0","type":"rich","title":"Q4","description":"This D3.js bubble chart visualizes the classic Iris dataset, plotting sepal length on the x-axis, sepal width on the y-axis, and encoding petal length through bubble radius. Each of the 150 flowers is colored by its species (setosa, versicolor, or virginica) using a categorical color scale, with a legend positioned to the right. The SVG chart includes interactive hover tooltips that display species and measurement details. The code loads data via `d3.csv`, uses `d3.scaleLinear` for axes and bubble sizing, and `d3.schemeCategory10` for color assignment, with animated tooltip transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d2e202c479cb463cbbba0dd15fbc49d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
