{"version":"1.0","type":"rich","title":"Activity6_Task3.2","description":"This example visualizes the classic Iris dataset as a scatter plot of sepal length versus petal length, coloring each point according to its species and using distinct fill symbols (circles, squares, etc.) to encode species, a shape legend appears on the right side. The implementation relies on D3 v7, using `d3.csvParse` to load the Iris CSV data, and then constructs the plot with `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.symbol` for the point glyphs, and `d3.axisLeft`/`d3.axisBottom` for the axes. The `viz.js` module manages loading state and fetch, while `axes.js` and `shapeLegend.js` encapsulate reusable drawing logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6493daf933b14ec0ab1bd9b5e892f46a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
