{"version":"1.0","type":"rich","title":"Activity6_tutorial3.2","description":"This example shows a scatter plot of iris flower measurements, with sepal length on the x-axis and petal length on the y-axis. Each point uses a distinct symbol shape to encode the species of the flower, and a custom legend explains the shape-to-species mapping. The visualization loads CSV data from a remote GitHub repository, parses it with `d3.csvParse`, and renders the chart using modular D3 v7 functions such as `scaleLinear`, `scaleOrdinal`, `symbolsFill`, `axisLeft`, and `axisBottom`. The code organizes its layout through reusable modules for axes, scatter plot, and a shape legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/81ca51cb360b44d29c146cae1b199b54?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
