{"version":"1.0","type":"rich","title":"EdX Viewer Data by Course with Stacked Bars, AY2013","description":"This example uses stacked bars to show the total number of video plays per course on EdX for the 2013 academic year, with each bar segment colored by the view counts’ country of origin, revealing the geographic distribution of engagement for each course. The visualization is built with the vega-lite-api, which registers Vega and Vega-Lite, and it loads CSV data from a GitHub-hosted dataset derived from the MITx-HarvardX Dataverse. The chart sums the ‘nplay_video’ field across courses, sorts courses by total views, and applies a sinebow color scheme to the country categories, with a custom config adjusting axis and label styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6fe8867fbdea4792a3972b4b86090cc4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
