{"version":"1.0","type":"rich","title":"activity8tutorial3.1","description":"This example shows a scatter plot of the Iris dataset, mapping sepal length to petal length and encoding species using different shapes via d3.symbol and a custom shape legend. The visualization loads the CSV data with d3.csvParse, updates the chart asynchronously through a state-based render pattern, and relies on d3.scaleLinear for axes positioning with d3.axisLeft and d3.axisBottom. Axes labels are generated manually, while the legend is built with d3.scaleOrdinal and symbolsFill, all within a scalable SVG that fills the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c43520c6e6548c0b1ddd4e3c3ec2d62?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
