{"version":"1.0","type":"rich","title":"EdX Viewer Data","description":"This scatterplot visualizes the number of plays per person against their active days on the EdX platform for the 2013 academic year, with a color legend identifying courses by viewer name. Built with React and D3 v5, it renders SVG circles positioned by `scaleLinear` scales for the x and y axes, while a sequential `scaleOrdinal` color scale encodes the categorical player names. The chart includes interactive hover highlighting that fades non-selected marks to 20% opacity, and it loads CSV data from a GitHub gist derived from the MITx-HarvardX Dataverse.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c974396e92949abb24abf4f01ced8d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
