{"version":"1.0","type":"rich","title":"Sophie's Polished Scatter Plot with Menus","description":"A scatter plot shows the relationship between various academic activity metrics—such as active days, video plays, and forum posts—from HarvardX and MITx course participants in 2013. Two dropdown menus allow users to select which attributes appear on the x- and y-axes. The visualization is built with React and uses D3’s `scaleLinear`, `extent`, and `scaleOrdinal` for axis and color scales, rendering as SVG with custom `Marks` components and tick-axis helpers. Gender is encoded via a two-color ordinal scale. Data comes from the MITx-HarvardX Dataverse.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/55906bc05a65476187b60bf0a761305c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
