{"version":"1.0","type":"rich","title":"question 4","description":"This visualization shows the correlation between sepal length, sepal width, and petal length across three Iris species using a bubble chart. Each circle represents a flower, with its x-position mapped to sepal length, y-position to sepal width, and radius scaled by petal length. Species are distinguished by color and identified in a legend. The code loads data from a CSV file and uses D3 v7 scales (`d3.scaleLinear`, `d3.scaleOrdinal`) and `d3.schemeCategory10` for coloring, with interactive tooltips on mouseover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cc686430438048e1a12b90fe27340aa6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
