{"version":"1.0","type":"rich","title":"question 4","description":"This example visualizes the correlation between iris flower measurements using a bubble chart, plotting sepal length against sepal width while encoding petal length through bubble size and species through color. It loads data from a CSV file and renders with D3 v7, using `d3.scaleLinear` for axes and bubble radius, `d3.scaleOrdinal` with custom colors for species, and `d3.axisBottom`/`d3.axisLeft` for scales. Interactive tooltips appear on mouseover via D3 event handlers, displaying species and petal length, alongside a legend for species identification.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3cb6e9d05d2246cfb469ecefaf5566e0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
