{"version":"1.0","type":"rich","title":"Tutorial 3.2","description":"This scatter plot shows the relationship between sepal length and petal length for three iris species, with each species represented by a distinct symbol shape and color. The visualization uses D3’s scaleLinear, scaleOrdinal, and axis utilities to position marks and render labeled axes. A shape legend, built with the d3.symbol API, identifies species symbols. The data is loaded from a remote CSV, parsed with csvParse, and rendered on an SVG canvas. The example demonstrates custom reusable components for axes and legends using the select and join pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1fda1e1559e2452b9ab90414ded9e570?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
