{"version":"1.0","type":"rich","title":"D3 : Lecture 2","description":"A scatterplot of the Iris dataset plots sepal length against sepal width, with each of the three species (setosa, versicolor, virginica) distinguished by a unique D3 symbol shape and color. The visualization encodes species using red crosses, green stars, and blue triangles, positioned via d3.scaleLinear axes. The code also computes per-species means and sums of squared deviations for linear regression calculations, though the regression lines are not rendered. Data is loaded from iris.csv and drawn as SVG paths using d3.symbol().","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8ec4dcd185fe501fc1f77d3f0d631cb9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
