{"version":"1.0","type":"rich","title":"鳶尾花散點圖","description":"This interactive scatter plot visualizes the Iris flower dataset, allowing users to select any combination of sepal and petal measurements for the x- and y-axes via dropdown menus and a plot button. Each point is colored by species—setosa in red, versicolor in blue, and virginica in green—using a predefined color mapping. The visualization is built with D3.js v7, using `d3.scaleLinear` for axis scaling and `d3.csv` to load the data from an external URL. The plot renders as SVG circles within a fixed 550×550 canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4dfe0819ff77412c8553dca2ed8a4a9e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
