{"version":"1.0","type":"rich","title":"Scatterplot Iris using different marks","description":"This scatterplot visualizes the classic Iris dataset, mapping sepal length and width along the x- and y-axes while encoding petal length with point size. The three iris species are distinguished by both color (using d3.schemeCategory20) and by different d3 symbol shapes (circles, crosses, diamonds, etc.) generated with the d3.symbol API. Axes are labeled, and a legend identifies the species using the same symbols and colors. A tooltip is defined but not activated. Built with D3 v4 and SVG, the chart demonstrates how multiple visual channels—position, size, color, and shape—can be combined in a single scatterplot. Data is the classic Iris dataset loaded from a CSV.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-ba9b80d3e5f2c2106af1fb68ce8fd325?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
